Radiation exposure due to incorporation of radionuclides in two selected places of the RSFSR five years after the Chernobyl accident

First results of a large-scale survey on the body content of radionuclides of Russian people during summer 1991 are presented. Data obtained for two villages of Klincy County (district of Briansk) are compared to those obtained in Klincy. An average body burden of 2 kBq, 3.7 kBq and 22 kBq Cs-137/134 has been found in Klincy town, Pestschanka and Weprin respectively corresponding to whole body doses of 0.08 mSv/a, 0.14 mSv/a and 0.88 mSv/a in 1991 resulting from incorporation of Cs-activities mainly through ingestion. The interdependence of environmental and body burden is discussed. (author)
