A natural person who, due to the nature of their duties, is likely to be exposed above the dose limits established for the public.

For radiation workers, the effective dose shall not exceed an average of 20 mSv over five consecutive years, and shall not exceed 50 mSv in any single year.

For members of the public, the effective dose shall not exceed 1 mSv per year. In special circumstances, up to 5 mSv per year is permitted, provided that the average over five consecutive years is 1 mSv.

Areas in which the annual dose received is likely to exceed 1 mSv are designated as radiation areas, and radiation areas are classified according to radiation levels as follows:

Controlled Areas: Areas in which the entry and exit of radiation workers are subject to special control and their work is subject to special rules from the point of view of radiation protection, and in which persons working with radiation by virtue of their duties may be exposed to a radiation dose exceeding 3/10 of the average annual dose limits for five consecutive years.

Supervised Areas: Areas in which 1/20 of the annual dose limits for radiation workers is likely to be exceeded but 3/10 is not expected to be exceeded, which do not require individual dose measurement but do require environmental radiation monitoring.

Activities within the scope of Law No. 7381 shall not be carried out without notifying the Authority or without obtaining an authorization from the Authority.

A licence must be obtained from the Authority in order to operate a nuclear facility, a radiation facility or a radioactive waste facility and to carry out radiation practices. Only citizens of the Republic of Türkiye or legal persons established under the legislation of the Republic of Türkiye may obtain a licence from the Authority. The matters for which a permit or an authorization certificate must be obtained are regulated under Article 4 of Law No. 7381.

Article 15, paragraph six, subparagraph (a) of the Regulation on Authorizations for Nuclear Facilities provides that “Within the scope of the manufacture of equipment subject to the approval of the Authority, the Organization shall also have semi-finished products determined by the Authority based on the graded approach manufactured by manufacturers who have received an authorization certificate from the Authority.”

Pursuant to the provision of Provisional Article 1, paragraph three of the Regulation on Authorizations for Nuclear Facilities, regulatory control over the manufacture of equipment and semi-finished products for the Akkuyu Nuclear Power Plant is carried out within the framework of the decisions of the Nuclear Regulatory Board dated 5/10/2022 and numbered 2022-61/4 and dated 20/9/2023 and numbered 2023-76/4. On this basis, it has been decided that the following shall be manufactured by authorized manufacturers:

• The 49 items of equipment determined as a condition of the Limited Operation Permit and the semi-finished products of those among them classified as Safety Class 1,

• Other equipment and semi-finished products classified as Safety Class 1,

• Equipment classified as Safety Class 2 and 3.

Manufacturers falling within this scope are obliged to obtain a Manufacturer Authorization Certificate.

The section entitled “Authorization of Manufacturers” of the “Regulation on Supply Chain in Nuclear Facilities”, which entered into force upon publication in the Official Gazette dated 1/8/2024 and numbered 32619, must be followed.

In order for the application process to commence officially, the application documents must be submitted to the Authority in hard copy. Discussions held with Authority staff by e-mail or through other communication channels do not mean that the process has officially commenced, and all responsibility for the application process rests with the applicant.

Article 12, paragraph three of the “Regulation on Supply Chain in Nuclear Facilities” provides that "Authorized persons shall notify the Authority of any requests for changes concerning the scope of the manufacturing for which they are authorized, changes regarding the facility where part or all of the manufacturing will be carried out and their corporate information, and other changes regarding their qualifications and competencies forming the basis for their authorization. Where deemed necessary by the Authority, the authorized persons shall apply for a renewal of the authorization certificate."

• Change concerning the scope of the manufacture for which authorization has been granted — an update to the list of equipment to be manufactured within the scope of the authorization (addition / change of safety class / etc.)

• Change concerning the facility where all or part of the manufacture is to be carried out and concerning corporate information — an update to the address of the manufacturing facility where the manufacture of equipment is to be carried out within the scope of the authorization (change of the address of the manufacturing facility / addition of a new manufacturing facility address / change of the head office address / etc.)

Article 13, paragraph one of the “Regulation on Supply Chain in Nuclear Facilities” provides that "If the authorization certificate requires renewal for any reason, the authorized person shall apply to the Authority with a petition detailing the request and justification. If there are updates to any documents previously submitted with the authorization application, the authorized person shall include the up-to-date versions of those documents with the petition.” Pursuant to that provision, the up-to-date versions of those documents submitted with the initial Manufacturer Authorization Certificate application which have changed must be submitted with the application in question. In addition, with regard to documents not submitted within the scope of the application, the statement “there has been no change in the documents not submitted since the initial authorization” must be added to the application petition.

Article 13, paragraph three of the “Regulation on Supply Chain in Nuclear Facilities” provides that “"Applications for renewal of the authorization certificate for the purpose of extending the validity period shall be submitted within six months prior to the expiration of the authorization certificate. If the application is deemed appropriate, the authorized person's authorization certificate shall be renewed for an additional five-year period. For authorized persons who submit a timely application for extension, their authorization remains valid until the Authority completes its evaluation." Pursuant to that provision, the relevant application for an extension of the period may be submitted within the six months preceding the expiry of the manufacturer authorization certificate, and no application for an extension may be submitted before that time.

Article 13, paragraph four of the “Regulation on Supply Chain in Nuclear Facilities” provides that "Persons who fail to submit a timely application for renewal to extend the validity period lose their right to renew the authorization certificate. However, they may reapply for a new authorization certificate in accordance with the provisions of this Regulation.”

More than one application may be submitted at the same time for the renewal of a manufacturer authorization certificate. However, pursuant to the provisions of Article 13 of the “Regulation on Supply Chain in Nuclear Facilities”, it is clear that the validity period of the authorizations of persons who apply only for an extension of the period will continue until the assessment by the Authority has been completed.

For applications concerning changes other than an extension of the period, activities may be continued only within the scope of the existing authorization until the authorization process relating to the change has been completed.

• For example: I have applied for a change to expand the scope of the equipment list; may I manufacture the new equipment covered by the application?

– No! The equipment subject to the application may not be manufactured until the relevant application process has been completed.

• For example: I have applied for a change concerning the facility where all or part of the manufacture is to be carried out; may I manufacture equipment at the relevant new facility covered by the application?

– No! Equipment may not be manufactured at the facility subject to the application until the relevant application process has been completed.

Companies authorized for the oversight of structures important to safety may also carry out the oversight of structures that are not important to safety. No separate authorization is required for this.

The obligations underlying the licence begin when the licence application for the radiation source is submitted and end when the radiation source is released from regulatory control. The authorized person is obliged to carry out activities in accordance with the scope of the authorization granted by the Authority, to ensure the continuity of the conditions of the authorization, and to remedy within the period given the findings identified by the Authority and notified to them. The cessation of business by the authorized person, or the restriction, suspension or revocation of their authorization, and similar circumstances do not relieve them of their responsibility.

Where termination of the licence is requested for radiation application in which no radioactive source is used, the licence shall be terminated if the information and documents concerning the final status of the radiation sources are submitted to the Authority and are found appropriate by the Authority.

As for radioactive sources, where the authorized person wishes to transfer the radioactive sources in their possession, the transfer of the radioactive source may be carried out only if the necessary notification is made to the Authority by the authorized person and the licence application submitted by the person who will take over is found appropriate by our Authority. If the source is not to be used within the organization, a copy of the official document evidencing completion of the export (bill of lading, customs export declaration, etc.), obtained after the source has been sent to the country of origin under an export permit, or a copy of the waste delivery record, obtained after delivery to the radioactive waste processing and storage unit of the TENMAK Nuclear Energy Research Institute for waste processing, must be sent to our Authority.

In accordance with the provisions of Article 20 of the Regulation on Authorizations for Radiation Facilities and Radiation Practices, radiation generating devices operating at a voltage of 30 kV and below are exempt from authorization obligations, that the dose rate does not exceed 1 μSv/hour (0.1 mrem/hour) at any point 10 cm from their surfaces accessible under normal operating conditions.

Radiation generating devices operating with a voltage above 30 kV may be exempted from the obligations regarding authorization by being evaluated by the Authority, provided that the dose rate does not exceed 1 µSv/hour (0.1 mrem/hour) at any point 10 cm away from the accessible surfaces under normal operating conditions and provided that they are used safely.

Detailed information on exemptions is available on our website at https://ndk.org.tr under the relevant menu > Services > Radiation Sources Authorization Activities> Exemptions or https://www.ndk.org.tr/en-US/exemptions.

For radiation sources to be operated at the same address, if the same type of licensing application is to be submitted, you may submit this application at one time and under a single session.

If the application fee has not been paid, you may ignore the previous application and create a new one.

If the application fee has been paid, you may send the missing documents to our Authority by post.

Our Authority cannot intervene in application forms. You may follow the steps set out in 8.13

The organization acquiring/purchasing the source must submit a licence application for the radiation source in question. See 8.10.

Spatial design approval must be obtained for the below before a licence application is submitted.

• Irradiation facilities

• Accelerator facilities

• Radioactive source preparation facilities

• Radiotherapy practices

• Nuclear medicine practices

• Industrial radiography practices in a shielded enclosure

• Areas established for the purpose of producing, maintaining and repairing radiation sources or of replacing radioactive sources

For the below, although it is not necessary to obtain spatial design approval before submitting a licence application, spatial design approval may be obtained if requested by the Organization.

• SPECT and SPECT/CT units in which nuclear medicine practices are carried out

• Rooms containing simulation devices used in radiotherapy practices

• Rooms in which radiology practices are carried out

The use of gammagraphy devices without a valid Type B package certificate is not permitted, and for devices falling within this scope the following procedures will not be carried out:

• Initial licensing, licence renewal, and changes to licence information/certificates,

• Transfer/delivery procedures for the devices,

• The import of radioactive sources to be loaded into the devices and source replacement.

Accordingly, the devices in question and the radioactive sources they contain must either be delivered to the TENMAK Radioactive Waste Facility for radioactive waste processing, following which a copy of the waste delivery record must be sent to the Authority, or returned to the country of origin (under an export permit and in a separate Type B package with a valid period), following which the document evidencing exit from customs abroad (bill of lading) must be sent to the Authority.

Where maintenance and repair activities are carried out at the premises where devices for which a use and possession licence has been obtained from the Authority are located, protection against exposure to radiation during the maintenance and repair services provided by technical services must be ensured under the responsibility of the holder of the use and possession licence for the devices (the authorized person) and of the party carrying out the maintenance and repair (the contractor), and measures must be taken, including where necessary the use of dosimeters and additional protective equipment; no licence needs to be obtained from the Authority for these maintenance and repair activities.

Where the production or the maintenance and repair activities of devices are carried out at premises such as factories, manufacturing plants and workshops, a licence must be obtained from the Authority to carry out these operations in order to ensure radiation protection during the manufacture or maintenance and repair of these devices and during source replacement operations.

The companies that will apply to the Authority to be evaluated within the scope of exemption must send a document (For example, type approval certificate issued by the German Federal Office for Radiation Protection –BfS-) showing that the dose rate measurements taken at a distance of 10 cm from all surfaces of the device by the authorized organizations (regulatory bodies in the country where the radiation sources are produced or organizations authorized by regulatory bodies) do not exceed 1 µSv/hour (0.1 mrem/saat), or a document indicating that the device has been exempted by the regulatory authirities. In addition, technical documents containing the kV, mA values of the device and the dose rate values read on the surfaces of the device should also be sent.

Within the framework of harmonization studies with the European Union Acquis carried out by the Authority, during activities related to the use of ionizing radiation sources, within the framework of ensuring parallelism with Directive 96/29/EURATOM dated 13.05.1996, which determines the principles for the protection of individuals, society and the environment from the harmful effects of ionizing radiation, for electrical devices that are deemed appropriate for use by the Authority taking into account their advantages against possible damages, in accordance with the provisions of the Article 20 of the Regulation, the notification obligation will continue and these devices may be exempted from the obligations regarding authorization.

Exemptions granted by the Authority may be revoked when deemed necessary in terms of radiation safety and the security of radioactive sources. An application for authorization is required for radiation sources whose exemption has been revoked.

The authorized person must ensure “the classification of radiation workers; the provision of the passive dosimeters to be used by those radiation workers classified as Category A, their correct and regular use, and their timely provision to the dosimetry service so that individual dose results are monitored and assessed and the workers are informed of their dose results; the regular medical surveillance of these persons; the carrying out of the necessary procedures in the event of exposure above the dose limits determined by the Authority for radiation workers; and, where necessary, the amendment of the duty schedule of personnel”.

That said, the requirement for a personal dosimeter varies according to each type of application (industry, medicine, security, etc.). The information and documents required for a licence should be examined on the website https://ndk.org.tr/tr/ under the heading “Services”.

The Authority does not provide dosimetry services. Dosimetry services must be obtained from organizations authorized by the Authority. Information on the organizations providing dosimetry services that have been authorized by the Authority is available on the Authority’s website via the menu steps Services > Radiation Sources Authorization Activities > Authorized Organizations (https://www.ndk.org.tr/yetkilendirilmis-kuruluslar-radyasyondan-korunma).

According to the principle of “Optimization”, one of the Basic Principles of the Dose Limitation System set out in the Regulation on Radiation Safety published in the Official Gazette dated 24/3/2000 and numbered 23999, in practices giving rise to exposure to radiation it must be ensured that the lowest possible dose is received, taking into account, for all possible exposures, the magnitude of individual doses, the number of persons to be exposed, and economic and social factors. In addition, pursuant to the provisions of the Regulation, protective clothing and equipment appropriate to the nature of the work performed must be used, and warning signs indicating the requirement to use such clothing and equipment must be displayed within controlled areas.

Personal protective equipment means all materials, tools, equipment and devices designed for that purpose which are worn, attached or held by the worker and which protect the worker against one or more risks arising from the work carried out that affect their health and safety.

In order to provide protection against ionizing radiation, protective equipment appropriate to the nature of the work performed is selected and used, taking into account the radiation application, the characteristics of the radiation source used in the application and the possible exposure situation.

Personal protective equipment generally provides individuals with a significant degree of protection. It is known that, where protective equipment is used continuously, a significant reduction in doses is achieved. Appropriate protective equipment must without fail be used in all cases where it does not prevent the work from being carried out.

The licence holder and the radiation protection officer are obliged to determine the personal protective equipment appropriate to the nature of the work, to provide it in sufficient quantities, and to take all measures to ensure that radiation workers use the personal protective equipment properly. Instructions for use must be prepared, and their implementation ensured, setting out which personnel are to use the protective equipment and when and how it is to be used, according to the application carried out. Radiation workers, for their part, are responsible for using the protective equipment in accordance with the training and instructions they have received.

Although not mandatory, the following room dimensions are recommended:

• For periapical dental X-ray devices, the room dimensions should not be smaller than 2 x 2 m².

• For panoramic and volumetric dental X-ray devices, the room dimensions should not be smaller than 2 x 2.5 m² (where the control unit is located outside the room and exposure is carried out from outside the room).

• For single-tube X-ray devices, the room dimensions should not be smaller than 3 x 5 m².

• For fluoroscopy devices, the room dimensions should not be smaller than 4 x 6 m².

• For angiography devices, the room dimensions should not be smaller than 4.5 x 6.5 m².

• For mammography devices, the room dimensions should not be smaller than 2.5 x 3.5 m².

• For bone densitometry devices, the room dimensions should not be smaller than 3 x 5 m².

• For whole-body computed tomography devices, the room dimensions should not be smaller than 4 x 5.5 m².

Services > Radiation Sources Authorization Activities > Licence (Radiation Facilities) or Licence (Radiation Practices)

An application for a change to the licence certificate must be submitted by the new Radiation Protection Officer via e-Government together with the required documents (see 8.10).

If there are radiation sources for which a licence renewal application must be submitted, the new Radiation Protection Officer must submit the licence renewal applications for those sources (see 8.10). Organizations that submit the licence renewal application in question with the new Radiation Protection Officer are not required to submit an application for a change to the licence certificate for the radiation source concerned on account of the change of RPO.

Where the institution, organization, company, etc. holding the licence changes, the former licence becomes invalid and a new licence application must therefore be submitted via e-Government.

See 8.10.

Where the title changes while the authorized person and the location remain the same (for example, a change of title of the same legal person as published in the Official Gazette), an application for a change to the licence certificate must be submitted via e-Government.

See 8.10 and 10.9.

The concept of licence holder refers to the natural or legal person to whom a licence, permit or authorization certificate has been issued by the Authority for the conduct of activities involving radiation sources. Where the natural or legal person under the conditions in which the licence was issued changes, this constitutes a change of licence holder and a new licence must therefore be obtained.

In this context, where a private practice is converted into a polyclinic, a new licence application must be submitted, since a conversion from a natural person to a legal person takes place. See 8.10 and 10.9.

An application for a change to the licence certificate must be submitted via e-Government, together with a copy of the document obtained from the municipality or similar body concerning the change of address and the other required documents (see 8.10).

See 8.10 and 10.9.

Where the address of mobile/portable devices changes, an application for a change to the licence certificate must be submitted.

In order to carry out the procedure for a change to the licence certificate, the application must be submitted via the page opened by selecting, in order, the following links on the website www.ndk.gov.tr;

• “Online Services” =>

• “e-NDK Services” =>

• “Licence, Permission, Approval and Inspection Services for Radiation Sources / Practices / Activities / Facilities” =>

• “Making Changes to Licence Certificates”

Provided that the validity period of the licence has not expired, the licence certificates relating to the radiation sources within your Organization are available on the website https://ndk.org.tr ;

•  from the “Online Services” menu,

•  via the “Licence Inquiry” link,

on the page that opens, after logging in with e-Government credentials by the persons assigned as Radiation Protection Officer (RPO) on behalf of your Organization and following the relevant steps.

• Sale or transfer of the radiation source

• Withdrawal from use and placement in storage of a device not containing a radioactive source

• Scrapping (HEK) of a device not containing a radioactive source

• Return of a radioactive source, or of a device containing a radioactive source, to country of origin

• Transfer of a radioactive source, or of a device containing a radioactive source, to a radioactive waste facility

• Closure/relocation/sale-transfer procedures for the unit in which PET, PET/CT, PET/MR, SPECT and SPECT/CT imaging devices are located

• Closure/relocation/sale-transfer procedures for a radionuclide therapy unit

A petition stating the name and full address of the organization to which the radiation source was sold or transferred and the necessary contact numbers must be sent to the Authority by post.

Termination of the licence does not relieve the licence holder of their obligations until the matters determined by the Authority have been fulfilled. The authorized person shall return their radioactive sources to their place of origin, or send them to a radioactive waste facility, or sell/transfer them to another person. A sale/transfer is carried out where notification is made to the Authority by the authorized person and the licence application submitted by the person who will take over is found appropriate by the Authority.

The responsibilities of the authorized person end upon release from regulatory control. The cessation of business by the authorized person, or the restriction, suspension or revocation of their authorization, and similar circumstances do not relieve them of their responsibility. In such cases, where the Authority assesses that a vulnerability has arisen in terms of safety, security and nuclear safeguards, any and all measures to ensure safety, security and nuclear safeguards may be required by the Authority to be taken, with the legal and financial responsibility resting with the authorized person.

Where radioactive sources are not used, it is not possible to store them. Such radioactive sources may under no circumstances be released into the environment, nor may they be finally disposed of by the authorized person; they shall be returned to their place of origin or, where this is not possible, delivered to a radioactive waste facility.

A copy of the record showing that the radiation source has been scrapped (HEK) must be sent to the Authority by post, attached to a petition.

Where mobile devices are transported to different provinces, the procedures set out at the link below must be carried out and the e-transport form must be completed and recorded.

https://www.ndk.org.tr/e-tasima-islemleri

A licence issued to a natural/legal person authorized by our Authority for a radiation facility or radiation application may not be transferred. This licence covers the activity of the sources for which the application was made, under the responsibility of the persons approved by the Authority and at the address specified in the application.

Where the organization official changes during the licence period, the Authority shall be notified in writing by means of a petition stating that there has been no change in the licence conditions, together with the application form relating to the practice concerned completed by the new organization official. The records relating to the change in question are updated by the Authority.

On the basis of the assessment to be made by our Authority, or where it is established that activities have been carried out without the licensing procedures having been completed, the provisions of Articles 24 and 25 of Nuclear Regulation Law No. 7381 and of the Regulation on Administrative Sanctions of the Nuclear Regulatory Authority may be applied.

Since the X-ray tubes of X-ray devices do not contain radioactive material, these tubes are not subject to the radioactive waste procedure required for radioactive materials. However, since X-ray tubes may contain chemical substances such as Beryllium (Be), they must be delivered, as chemical waste, to recovery/disposal facilities licensed under the Regulation on Environmental Permits and Licences, which entered into force upon publication in the Official Gazette dated 10/9/2014 and numbered 29115 by the Ministry of Environment, Urbanisation and Climate Change.

The import, export or transport of radioactive materials is subject to regulation by the Nuclear Regulatory Authority (NDK) in accordance with the existing legislation set out below.

• Nuclear Regulation Law No. 7381 dated 5/3/2022 and Presidential Decree No. 95 on the Organisation and Duties of the Nuclear Regulatory Authority

Since radioactive materials fall within the class of dangerous goods, activities relating to the transport of such materials are also subject to the provisions of the legislation on the transport of dangerous goods administered by the Ministry of Transport and Infrastructure.

First, an application must be submitted for a use and possession licence for the radioactive source, or the device containing a radioactive source, that is planned to be imported, in order for it to be used and possessed within the borders of our country. Subsequently, an import permit must be obtained from the Nuclear Regulatory Authority (NDK) in order for the radioactive sources or the devices containing radioactive sources in question to be imported.

If the radioactive source to be imported, or the device in which the radioactive source is contained, falls within the exemptions set out in Article 20 of the Regulation on Authorizations for Radiation Facilities and Radiation Practices, the import permit application shall be submitted;

• by organizations that have obtained a licence from the NDK for the import, export and transport of radioactive sources, or

• by the user organization that will use the radioactive source concerned only in its own activities, without any intention of sale to other organizations.

If the radioactive source to be imported, or the device in which the radioactive source is contained, does not fall within the exemptions set out in Article 20 of the Regulation on Authorizations for Radiation Facilities and Radiation Practices, then, before the import permit application, an application for a use and possession licence must be submitted to the NDK by the organization that will be the user of the radioactive source or of the device containing a radioactive source in the country, and that application must be found appropriate by the NDK. The import permit application for radioactive sources or devices containing radioactive sources that meet this condition shall be submitted;

• by the organization that has obtained a licence from the NDK for the import, export and transport of radioactive sources, or

• by the user organization that has obtained a use and possession (UP) licence from the NDK for the use or possession of the radioactive source or of the device containing a radioactive source, or whose licence application has been found appropriate by our Authority.

All licence applications to the NDK are submitted via e-Government.

The customs tariff headings relating to radioactive materials or related materials that are subject to the permission of the NDK pursuant to Law No. 7381 are published each year in the Official Gazette by the Ministry of Trade.

No permit is required from the NDK for the import of X-ray devices under GTIP number 9022.19 or X-ray tubes under GTIP number 9022.30. The practice of issuing licences by the NDK to organizations carrying out import and export activities involving X-ray devices has also been discontinued.

An export permit must be obtained from the NDK in order for radioactive sources or devices containing radioactive sources to be exported.

The export permit application for radioactive sources or devices containing radioactive sources shall be submitted;

by the organization that has obtained a licence from the NDK for the import, export and transport of radioactive sources, or

by the user organization that has obtained a use and possession (UP) licence from the NDK for the use or possession of the radioactive source or of the device containing a radioactive source.

Import-Export-Transport licence applications to be submitted to the NDK by organizations carrying out the activity of importing, exporting and transporting radioactive sources within the scope of radiation practices are submitted via e-Government. Applications must be submitted by the Radiation Protection Officer (RPO) of the organization that will obtain the licence, using their own e-Government password.

Services > Import/Export/Transport Activities > Import Permit > Radioactive Sources

or https://www.ndk.org.tr/ithal-izni

Following the e-Government application, an application must also be submitted via the Single Window Portal System of the Ministry of Trade.

In respect of the import permit application submitted to the NDK via e-Government, an application must be created in the Single Window System using the documents coded 0852 (SWS-NDK Certificate of Conformity (Deductible)) for unsealed radioactive sources and 0893 (SWS -NDK Certificate of Conformity (Single Use)) for sealed radioactive sources (https://uygulama.gtb.gov.tr/TekPencere) and submitted for the approval of the NDK. (Applicant Organizations must enter the number of the relevant e-application submitted to the NDK (e.g. 2026.01.000XXX) and the application date into the “document code” field of the document to be created in the SWS. The implementation guide relating to the document to be created in the SWS and its content is available at the following link. https://www.ndk.org.tr/ithal-izni

If your application in the SWS has been approved by the NDK, no change may be made to the information in the content of the SWS document (customs information, regime code, line content, etc.). You must submit a new application to the NDK via e-Government containing up-to-date and accurate information, submit a new Single Window application associated with that application, and submit it for the approval of the NDK.

If your application in the TPS has not been approved by the NDK, you may withdraw your application and update the information in the content of the SWS document.

Where approved applications have expired, a new application must be submitted to the NDK via e-Government and the Single Window.

After the export permit has been obtained from the NDK, the NDK must be notified as to whether or not the export operation has taken place. Within fifteen days at the latest following the export of the radioactive sources, the permit-holding organization must send to the NDK the customs declaration evidencing completion of the export, a screenshot of the single window, and the document showing that the company abroad has taken delivery of the radioactive source.

In order for an import/export permit to be granted for radioactive sources, the organization submitting the application must hold an Import/Export/Transport (IL) licence, or be an Organization holding a Use and Possession (UP) licence, or be an organization whose Use and Possession (UP) licence application has been found appropriate by the NDK.

If you do not hold a UP or IL licence, you may not import/export radioactive sources.

If you submit an import/export permit application as a user organization, in order for the radioactive source or device to be transported to your licence address you must obtain a service from a company holding a Transport Licence (TL) or an Import/Export/Transport Licence (IL) from the NDK for the transport of radioactive sources.

If you hold an Import/Export/Transport licence, you may apply for an import/export permit and carry out the transport yourself.

Radioactive materials are classified, packaged and labelled in accordance with the matters set out in the Regulation on the Safe Transportation of Radioactive Material and are transported by organizations that have obtained the necessary authorizations from the NDK pursuant to the relevant legislation.

Unsealed radioactive sources imported from abroad, or taken delivery of from their producer in the country, by user organizations that have obtained a licence from the NDK to use and possess them in their own facilities or practices may not be transferred, sold or transported to another user organization unless otherwise specified by the NDK in the licence conditions.

Sealed radioactive sources or devices containing sealed radioactive sources may be transported between user organizations that have obtained a licence from the NDK to use and possess these radioactive sources in their own facilities or practices, by a company holding an Import/Export/Transport Licence (IL), after notification has been made to the NDK regarding the sale or transfer of the radioactive source in question between user organizations and the assent of the NDK has been obtained. Mobile devices containing sealed radioactive sources may likewise be transported by these user organizations after the assent of the NDK has been obtained regarding their sale or transfer between users.

Without prejudice to the right of the NDK to impose a limit on the total quantity, the transport of radioactive materials whose total activity or activity concentration value exceeds the activity or activity concentration values determined pursuant to Annex-1 to the Regulation on the Safe Transportation of Radioactive Material for exempt material or excepted packages shall be carried out by organizations that have obtained a licence from the NDK, within the framework of the conditions determined by the NDK depending on the characteristics of the radioactive source.

The transport of portable devices containing sealed radioactive sources may be carried out by user organizations that have obtained a licence from the NDK to use and possess these devices, only for their own devices and provided that they make the notifications determined by the NDK.

For the transport of radioactive sources whose activities are above the activity levels determined by the NDK and which are regarded as “high-activity radioactive sources”, whether within the scope of their import or export or between organizations within the country, a transport permit must be obtained from the NDK for each transport by organizations that have obtained an Import/Export/Transport Licence (IL), before the transport activity is carried out. Transport within the country of radioactive sources that are not high-activity is carried out by organizations that have obtained an Import/Export/Transport Licence (IL) from the NDK without obtaining a separate transport permit.

Where an import or export permit application is submitted for high-activity radioactive sources, no separate transport permit needs to be obtained; the information and documents relating to the transport are sent to the NDK within the scope of the import or export permit.

Detailed information on high-activity radioactive sources is available at the following link:

Transit Permit applications are submitted via e-Government and must be submitted by the Radiation Protection Officer (RPO) of the organization that will obtain the permit. The information and documents that will be requested in the application are available at the following link:

Services > Authorizations for Import/Export/Transport Activities > Transit Permit

or https://www.ndk.org.tr/transit-gecis-izni

Pursuant to Nuclear Regulation Law No. 7381 and the relevant legislation in force, a licence must be obtained from the NDK in order to transport radioactive sources.

Licensed organizations must obtain a separate permit from the NDK for each import, export or transit of radioactive sources. Only citizens of the Republic of Türkiye or legal persons established under the legislation of the Republic of Türkiye may obtain a licence from the NDK.

For the transit of radioactive materials through Türkiye, an application for a transit permit may be submitted by an organization that has obtained a licence from the NDK for the import, export and transport of radioactive sources. You must therefore contact a licensed organization; that licensed organization may submit the application for a transit permit for radioactive materials via e-Government on your behalf.

If your application has not yet been assessed, you may send the NDK a petition setting out your request for cancellation of the relevant application and a refund of the fee. If your application has been assessed and your permit has been issued via the TPS, no refund of the fee is made.

In order for an import permit to be granted for devices containing radioactive sources, an application for a use and possession licence must first be submitted to the NDK via e-Government by the organization that will be the user of the device in question, and the application must be found appropriate by the NDK. Once the licence application has been found appropriate, you may apply for the import permit, again via e-Government.

The licence of an exported device containing a radioactive source is terminated. For this reason, an application for a use and possession licence must be submitted via e-Government before applying for an import permit. Once the licence application has been found appropriate, an application may be made for the import permit.

For the temporary exit from the country and entry into the country of industrial radiography devices containing radioactive sources for the use and possession of which a licence has been obtained from the NDK, an application for a temporary exit-entry permit must be submitted to the NDK via e-Government by the organization that has obtained a licence from the NDK to use and possess the devices.

For industrial radiography devices containing radioactive sources for the use and possession of which in free zones a licence has been obtained from the NDK to be brought into the country for the purpose of source replacement and re-entered into the free zone, an application for a temporary entry-exit permit must be submitted to the NDK via e-Government by the organization that has obtained a licence from the NDK to use and possess the devices.

The circumstances in which the licence terminates are set out below:

For devices that have been sent abroad following the granting of a temporary exit-entry permit but have not been brought back into the country within the validity period of the use and possession licence, a use and possession licence application must be submitted and an import permit obtained in order to bring them back into the country.

For portable devices containing radioactive sources that have been sent abroad following the granting of a temporary exit-entry permit but have not been brought back into the country within the validity period of the temporary exit-entry permit, an import permit and a new use and possession licence must be obtained in order to bring them back into the country.

Where a device has been sent abroad following the granting of a temporary exit-entry permit and the radioactive source inside the device is replaced abroad, the temporary exit-entry permit loses its validity, and an import permit and a new use and possession licence must be obtained before the device, together with the new radioactive source inside it, enters the country. In such applications, documents evidencing that the old source removed from the device has been delivered to its place of origin or to its manufacturer must be notified to our Authority.

Where the acts listed in Articles 24 and 25 of Law No. 7381 are committed, judicial and administrative sanctions are applied.

Nuclear materials and equipment and materials especially designed or prepared for the nuclear fuel cycle fall within the scope of the Regulation on Nuclear Safeguards.

Nuclear material accounting and control is applied to nuclear materials of a composition and purity suitable for nuclear fuel manufacture and for enrichment. In this context, nuclear material accounting and control is applied to uranium and thorium containing the mixture of isotopes occurring in nature, and to depleted uranium, thorium, any of these in the form of metal, alloy, chemical compound or concentrate, and other materials containing one or more of the aforementioned materials in a proportion to be determined by the Authority, as well as to plutonium-239, uranium-233, uranium enriched in the isotopes uranium-235 or uranium-233, any material containing one or more of these, and other fissile materials to be determined by the Authority.

Nuclear material accounting and control is commenced by the Authority where nuclear material of a composition and purity suitable for nuclear fuel manufacture and for enrichment is produced, imported or detected at any location.

Nuclear materials or especially designed equipment that merely pass in transit across the borders of Türkiye are not subject to this regulation.

The nuclear material accounting and control system is the system that ensures that, at locations defined in the field of nuclear safeguards as facilities or locations outside facilities, the following are recorded and verified in respect of nuclear material:

• its quantity,

• where it is located,

• how and for what purpose it is used,

• when it enters or leaves the facility or location outside facilities.

The establishment and operation of the nuclear material accounting and control system at facilities and locations outside facilities is the obligation of the person responsible for the facility/location outside facilities.

Pursuant to the Regulation on Nuclear Safeguards;

Facility means nuclear reactors, critical facilities in terms of nuclear fission; conversion, enrichment, fuel fabrication, reprocessing plants within the scope of nuclear fuel cycle, and relevant storage facilities as well as any location where nuclear material in amounts greater than one effective kilogram is used.

Location outside facilities (LOF) means any installation which is not a facility, where nuclear material is handled, used, stored, produced or processed in amounts of one effective kilogram or less, and the definition of effective kilogram is available in the Regulation on Nuclear Safeguards.

The facility or LOF responsible person is, for facilities, the authorized person whose duties and responsibilities are determined pursuant to the Regulation on Nuclear Safeguards and, for locations outside facilities, the operating person.

The facility or LOF responsible person is responsible for;

• Carrying out the activities relating to nuclear material accounting and control and making notifications to the Authority,

• Ensuring that all records and reports are kept accurately,

• Designating the person responsible for nuclear material accounting and control and ensuring that they receive the necessary training,

• Determining the material balance areas and key measurement points to be established for the purpose of determining the flow and stocks of nuclear material,

• Carrying out physical inventory taking,

• Carrying out internal inspection,

• Preparing the notifications, records, reports and procedures to be prepared pursuant to the Regulation on Nuclear Safeguards and ensuring that they are notified to the Authority in a timely manner.

A person appointed by the facility or location outside facilities at facilities and locations outside facilities and possessing the following attributes:

• Having sufficient capacity, documented at intervals and by methods to be determined by the person responsible for the facility or location outside facilities, in terms of mental alertness, emotional stability, communication skills enabling them to perceive audible, written and visual warnings and to express themselves, and physical mobility.

• Being a graduate of one of the engineering or basic sciences disciplines of universities providing at least four years of undergraduate education, or of higher education institutions in the country or abroad whose equivalence is recognized by the competent authorities.

• Having attended a nuclear material accounting and control training course or information seminar organized by the Authority or the International Atomic Energy Agency (IAEA).

The DIQ is an official document, in the format of the IAEA, containing all the design details of a facility, the flow of nuclear material, the measurement points and the nuclear material accounting and control system.

The DIQ must be submitted to the Authority;

• for facilities to be newly established, at least two hundred and forty days before construction begins,

• before the first entry of nuclear material into the facility, updated in accordance with the design,

• within thirty days of each change.

The Information Questionnaire for Locations Outside Facilities is an official document, in the format of the IAEA, containing all detailed information relating to the location outside facilities.

The Information Questionnaire for Locations Outside Facilities must be submitted to the Authority;

• fifteen days before the first entry of nuclear material,

• within thirty days where a change occurs.

Exemption from nuclear material accounting and control applies only to nuclear materials having the following characteristics:

• Nuclear materials used as sensing components in devices, in amounts up to or less than

• gram quantities,

• Plutonium with a plutonium-238 content exceeding 80% by mass.

• Nuclear materials to be used for non-nuclear purposes.

For an exemption, a request for exemption must be submitted to the Authority by the person responsible for the facility or location outside facilities. If the exemption is found appropriate by the Authority, the exemption is applied to the nuclear materials in question. Materials covered by an exemption may not be used or processed other than for the stated purpose and may not be stored together with nuclear materials subject to nuclear material accounting and control. Upon the request of the person responsible for the facility or location outside facilities, or where the Authority determines that the conditions for exemption are not met, the Authority may withdraw the exemption.

Where nuclear materials of a composition and purity suitable for nuclear fuel fabrication and for enrichment are produced or imported or detected, nuclear material accounting and control is commenced for the materials in question. Following the commencement of nuclear material accounting and control, the obligations set out in the Regulation on Nuclear Safeguards are fulfilled by the facility or location outside facilities responsible person.

Nuclear material accounting and control is terminated for nuclear materials that have been exported and for nuclear materials that are determined to have been diluted in such a way that they can no longer be used in any nuclear activity, or to have become a waste from which nuclear material can no longer be recovered.

Nuclear material at a facility or location outside facilities may be transferred only to another facility or location outside facilities. For the transfer, an application must be submitted to the Authority with the following information and documents before the transfer of nuclear material takes place:

• The amount, physical form, chemical composition, enrichment or isotopic composition and utilizations purpose.

• The name of the facility or LOF to which the transfer will be made, the shipping date, and letter of undertaking that the transferee accepts the transfer

• The mode of transport and carrier company information.

• The number of transport packages.

• Method of fulfilment of physical protection requirements in accordance with the relevant legislation,

• Other information and documents that may be requested by the Authority in this context.

The transfer of nuclear material is carried out within the scope of the permit granted by the Authority.

Before the export and import of nuclear material takes place, in addition to the permit application to be submitted to the Authority, notification must be made to the Authority at least thirty days before the nuclear material enters or leaves Türkiye.

The notification to be made to the Authority must include;

Base stations, air traffic control radars, microwave ovens, TV station masts, cordless telephones, computer screens, electrical household and kitchen appliances, power lines, MR imaging systems and high-frequency transmission lines and the like are non-ionizing radiation sources.

For this reason, since the fields in question do not contain a radiation source that would give rise to the generation of ionizing radiation, they do not fall within the scope of our Authority’s regulatory and supervisory activities.

The arrangements relating to non-ionizing radiation are set out in the Regulation on the Protection of the Environment and Public Health from the Adverse Effects of Non-Ionizing Radiation, published in the Official Gazette dated 24/7/2010 and numbered 27651; in this framework, it is considered that a request for information may be made to the Ministry of Environment, Urbanisation and Climate Change, the Ministry of Health and the Information and Communication Technologies Authority.

The concentration values of the ozone and nitrogen oxide gases generated in radiology laboratories are below the threshold values. For this reason, it is not mandatory to install a ventilation system in these laboratories for the removal of harmful and toxic gases arising as a result of radiation practices.

However, radiation safety must be assessed as a whole together with the culture of occupational safety. Since the culture of occupational safety covers all systematic activities aimed at protection from all factors that may harm human health during work and at the improvement of the working environment, the presence of a ventilation system in the working area becomes essential from the point of view of hygiene.

Standards or mandatory legal requirements relating to heating, cooling and ventilation installations in the clinics and private practices where radiology practices will be carried out are not related to our Authority’s licensing conditions; the regulations of the Ministry of Health or of the Ministry of Labour and Social Security on this subject should be examined.
