Official personal dosimeter for national guests

Before you fill out the form, please read the Strahlenschutzanweisung for guest scientiest and employees of external companies.

In general, regardless of whether the person is classified in category A or B, access to the GSI radiation protection areas requires a radiation protection examination (not older than 12 months) and GSI online radiation protection instruction (also not older than 12 months).

Guest scientists and employees from external companies need to bring their own official dosimeter to GSI. Are there any important reasons why they can not bring their own dosimeter to GSI, it is possible to get a dosimeter from GSI. Precondition is that they have a Strahlenschutzregisternummer / Radiation Protection Register Number (SSR-Number). If they do not have a SSR-number, the employer must apply one.

If you have questions please contact Alexandra Knapp.

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.

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.
