the Evaluation of Revised Project Shielding in Licensed Units and Facilities


In case the following changes are made in the projects of accelerator facilities, radioisotope and radiopharmaceutical production facilities, PET, PET/CT and Inpatient treatment units; the changes are notified to the NDK by the applicant company.

The applicant company is required to send following forms with the Revised Architectural Project CD in dwg format for application.

For Accelerator Facilities

  • Changing the location and size of the cyclotron room, changing the device characteristics or increasing the production capacity
  • Addition of New cyclotron room
  • Changing the location and size of the production laboratory or adding a new synthesis cell, a second production laboratory
  • Quality control, changing the location and size of the solid radioactive waste room or adding a new room for the same purpose

Radioisotope Production or Radiopharmaceutical Preparation Facilities

  • Changing the location and size of the production laboratory or adding a new synthesis cell, a second production laboratory
  • Quality control, changing the location and size of the solid radioactive waste room or adding a new room for the same purpose

PET and PET/CT units

  • Changing the location of current PET and PET/CT
  • Any Change in current dose rate in the room (for example changing PET with PET/CT system) or any device change
  • Addition of new imaging device
  • Changing the hot cell location and size
  • Addition of new hot cell
  • Change in size and the location of the following rooms; radioactive patient waiting room, injection room, patient toilet, late imaging room and waste room additional of a new room

Inpatient Treatment Units

  • Changing the location and size of the inpatient treatment room or adding a new treatment room
  • Addition of new treatment room for Lu-177, In-111 etc.to current I-131 treatment room
  • Change of size or location of hot cell
  • Addition of a new hot cell.
  • Change in the location of solid waste room or addition of a new room.


  • “Application project CD in dwg format (site plan, floor plans, sections)", prepared in accordance with the Required Issues in the Architectural Project for Shielding of Accelerator Facilities, containing information on the layout and shielding of the facility (annex-1.1)
  • Shielding Conformity Report Application Form of Accelerator Facilities for the acceleration facilities (Annex 1-2)
  • Detailed information and catalog specifying the technical specifications of the cyclotron device(s) and production cells
  • Flow chart showing procedures in detail covers; production, packaging, distribution, liquid and solid waste system, ventilation and chimney system etc. in the facility. Flow chart showing procedures in detail


  • "Application project CD in dwg format (site plan, floor plans, sections)", prepared in accordance with the Required Considerations in the Architectural Project for shielding of Radioisotope Production or Radiopharmaceutical Preparation Facilities, containing information on the layout and shielding of the facility (Annex-2.1)
  • Shielding Conformity Report Application Form for Radioisotope Production or Radiopharmaceutical Preparation Facilities for radioisotope and radiopharmaceutical production facilities (Annex2.2)
  • Detailed information and catalog on the equipment of the facility
  • Flow chart showing procedures in detail covers; production, packaging, distribution, liquid and solid waste system, ventilation and chimney system etc. in the facility
Note: The shielding conformity report is not mandatory for simulation devices.

In the license application, It is sufficient to send the project, which shows the room where the simulation device is installed and the adjacent areas, and which has been prepared in accordance with the Requirements to be included in the Architectural Project Regarding the Shielding of the Rooms of the Radiotherapy Practices and/or the Simulation Devices (Annex-3.1)

It is sufficient to send the architectural project prepared in accordance with the Requirements to be in the Architectural Project (Annex-4.1) regarding the Shielding of Nuclear Medicine Units (Diagnostic and Outpatient Treatment), showing the rooms and adjacent areas in the SPECT or SPECT/CT units.


Note: It is not mandatory to receive a “Shielding Conformity Report” from the Authority. In the license application, the architectural project showing the room and adjacent areas where the radiation source will be used and kept should be prepared in accordance with the Required Items in the Architectural Project (Annex-6.1) and sent to the Authority. In order to provide practical information about shielding to the companies for the rooms where the radiology devices will be installed, standard room sizes and shield thicknesses that may be sufficient depending on the type of device, workload and shield material. It is given in detail in the document named (RSGD-KLV-007). Organization may determine the shielding conditions before applying for a license by using this document.
