Radiation Protection Register; application for the personal identification number

A personal identification number (SSR number) is required for entries in the Radiation Protection Register (SSR). You must apply for this number at the Federal Office for Radiation Protection.



You are in the employing company of the occupationally exposed persons:

  • person responsible for radiation protection
  • person obligated or responsible according to the Radiation Protection Act or
  • an appropriately authorized person, e.g. radiation protection officer or radiation protection officer


You can only apply for SSR numbers electronically:

  • Register at the SSR portal of the Federal Office for Radiation Protection.
  • After registration, your access data for the BfS portal will be sent to your personal e-mail address.
  • Call up the SSR portal and log in with your access data.
  • Select the "Data Entry" section and enter the information of the persons for whom you want to apply for an SSR number. This is possible by
    • type in the data or
    • insert the data via CSV or TXT file.
  • Click on "Generate".
  • You will now find the newly created SSR number(s) and the associated data in the "Data Output" area.
    • Note: If you uncheck the "Show new records only" box, you will see all the SSR numbers you generated.
  • Mark all records you want to download with a check mark. Then click on "Download zip file".
  • In the zip file you will find
    • a list of the selected SSR numbers as a CSV file.
    • a certificate for each employee. You must give the certificates to the employees immediately (printed or as a PDF file). The employees must keep their certificates.

Online procedures


  • There are no costs involved.


There are no legal remedies. The purpose of the personal identification number is unique identification. Reports to the Radiation Protection Register can thus be clearly assigned to a person. The personal identification number has no binding effect on the outside. Consequently, the assignment of the personal identification number is not an administrative act against which an appeal would be admissible.
