Apply for authorisation to work in external facilities or installations with exposure to ionising radiation
If you work as a company or sole trader in a plant or facility or employ persons in which exposure to ionising radiation can lead to an effective dose of more than 1 millisievert per calendar year, you must apply for a permit.
In this case, the persons are considered to be occupationally exposed persons.
For activities in connection with the operation of third-party X-ray equipment and sources of interference, you can choose between this authorisation in accordance with Section 25 of the Radiation Protection Act (StrlSchG) and a notification in accordance with Section 26 StrlSchG.
The licence is usually valid nationwide.
The licence applies to you if you have a company that carries out repair or maintenance work in nuclear power plants, for example, or a cleaning company that works in a nuclear medicine facility.
Persons may only be employed in external plants or facilities once authorisation has been granted and, as a rule, each person to be employed is in possession of a radiation pass.
The authorisation is limited to a maximum of five years.
Responsible authority
The regional council in whose district your company or business is located.
