Procedure of Monitoring of Internal Exposures

For the handling of sources of ionising radiation, dose limits for the workers have been laid down in the Radiation Protection Act (Strahlenschutzgesetz - StrlSchG). For work-related exposure to ionising radiation the limit value of the effective dose is 20 mSv per calendar year. When handling open radioactive substances, the body dose can be composed of external and/or internal radiation exposure, depending on working conditions, the chemical form of the used substances and the type of radionuclides.

Monitoring of flight personnel

At high altitudes people are exposed to considerably more cosmic radiation than at ground level. It is technically not possible to shield aircraft against cosmic radiation. Thus, pilots and flight attendants - especially if they often fly long-haul flights on polar routes - may receive radiation doses which are certainly comparable to the dose values of occupational groups using ionising radiation or handling radioactive sources.
