Occupational radiation exposure in the GDR in 1981

As in the previous year, the centralized monitoring of radiation workers for occupational exposure was carried out on the basis of film badges (38,415 persons), measurements with a whole-body counter and analyses of biosamples (252 persons in all). According to the film data, the monthly exposures exceeding 4 mGy totalled 645 including 41 doses higher than 10 mGy. Five workers received annual doses above 50 mGy, with the highest values being 840 mGy. For the exposed population as a whole and some sub-groups, annual collective and mean annual doses have been given. In assessing internal exposure situation, use has been made of both data from the centralized monitoring program and those determined by some nuclear facilities themselves under the auspices of the SAAS. The results gave no indication of internal doses exceeding the annual limits of intake. (author)
