Official personal dosimeter for international guests


With the application form, we ask for personal information, contact information, GSI online instruction information, and medical examination regarding radiation protection. According to the new Radiation Protection Act (§ 170 StrlSchG), there are important changes for all persons supervised by the GSI from 31.12.2018:

In addition to the name, first name, date of birth and place of birth, the radiation protection register number (in the following SSR number) will be sent to our evaluation office. If there is no SSR number generated yet, the social security number as well as the birth name will be needed if an official dosimeter has to be issued.

Further information can be found on the website of the Federal Office for Radiation Protection:


All fields marked with an asterisk * are mandatory.

Personal data

Please enter your social security number here
  • Notes, where you can find your social security number (§ 147 SGB VI):

    If you have already worked in Germany, you have a social security number (= identical with the pension insurance number). The social security number is required to apply for the SSR number. You can find the social security number:

    • on the payslip
    • on the pension information letter or directly from the Deutsche Rentenversicherung ( or phone.: 0800 1000 4800)
    • you can ask any statutory health insurance company, even if you are not insured there
  • How is the SSR number created for persons who do not have a social security number?

    • If you do not have a German social security number, then we need a lifelong unchangeable person related registration number to create the SSR number, e.g. the Tax-Identification-Number (TIN) Here are some examples: Italy = CIF / Spain = DNI / France = NIF / Poland = PESEL / Belgium = NN / Bulgaria = UCN / Denmark and Greece = CPR / Ireland = PPS.
Please enter your foreign identification number

Note: If you have been in radiation protection monitoring since 1.1.2019, you have an SSR number. Please contact the company or the facility in which you were in the monitoring.

If you have not yet been in radiation protection monitoring this year, please contact the radiation protection of your company or institute.

Please tell us, in which badge box you would like to have your badge in. You find a list of all locations under the button send form.

Your radiation passport states whether you are classified in category A or category B. If you do not have a radiation passport, please ask your responsible radiation protection officer.

Location of dosimeter boxes

The badge will be deposited in one of the 25 badge boxes. These badge boxes are the blue boxes you find in the corridors, where the badges are stored while you don’t need it. Because we want to take a badge box which is near your office or near your laboratory, we ask you tell us, which badge box you like to have your badge. A list of locations of all badge boxes can be found here.
