National Dose Register (SSR)

The German National Dose Register (in German "Strahlenschutzregister", SSR) is a central federal institution and is operated by the Federal Office for Radiation Protection (BfS). It continuously monitors the dose limit values for occupationally exposed persons in Germany and the issuance of radiation passbooks.

National Dose Register - Overview and contact

The National Dose Register (SSR) contributes to the radiation protection monitoring of workers who are occupationally exposed to ionising radiation. The Federal Office for Radiation Protection (BfS) thus fulfils a legal task that was previously defined in the Atomic Energy Act, and is now defined in the Radiation Protection Act.

Information on the new legal requirements in occupational radiation protection

With the coming into force of the Radiation Protection Act (Section 170 StrlSchG) there were important changes with regard to the data that have to be submitted to the National Dose Register. Since 31 December 2018, all individuals subject to registration in the National Dose Register (persons, subject to occupational exposure) need a unique personal identification number: the National Dose Register Number (SSR Number). The SSR Number facilitates and improves the allocation and balancing of individual dose values from occupational radiation exposure in the National Dose Register. It also replaces the previous Number of the Radiation Passbook.
Since 31 December 2018 it is possible to apply for the SSR Number at the BfS.

The address of the SSR Portal for the application for the SSR Number is:

The SSR Number - basic information and how to apply for it

The SSR Number is a unique identification number used in occupational radiation protection based on the new legal requirements.

Since 31 December 2018 the BfS provides an encrypted and password protected web portal for the application for the SSR Number. In a first step, the responsible person needs to register in the ssrportal.

Statistical evaluations from the National Dose Register

Between 1997 (beginning of the central collection of occupational doses in Germany) and 2022, the amount of monitored employees per year has grown by about 28 %. In 2022, approximately 424,000 people were occupationally monitored for radiation protection. Compared to the year 2021, the number of monitored persons remained at a comparable level.
