Abstract

The paper presents the results of estimating the absorbed dose rate from incorporated 137Cs in the muscle tissue of European roe deer living in territories with different densities of radioactive contamination. Sampling was carried out during 1991–2007 in the territories of Bragin, Narovlyansky and Khoiniksky districts, Gomel region. The control sample consisted of samples obtained in the Gomel region. An increase of the 137Cs contamination density leads to a nonlinear increase in the absorbed dose rate. Regardless the density of radioactive contamination of animal habitats, there is a high variation in the absorbed dose rate, which persists throughout the entire period of research. In the territory with a radioactive contamination density of 137Cs below 555 kBq/m2 during the observation period, no excess of the absorbed dose rate of internal radiation in the muscle tissue of roe deer above the critical screening value was found. Roe deer inhabit this territory with a low probability of dose effects. At the same time, the probability of fluctuations in the absorbed dose rate remains in the exclusion zone, the value of which goes beyond the screening value, which increases the probability of weak cytogenetic effects, affects the morbidity and reproductive system of animals.
