Razanov Serhiy Fedorovich – Doctor of Agricultural Sciences, Professor of the department of ecology and environmental protection of Vinnytsia National Agrarian University (21008, Vinnytsia, Sonaychna St., 3, e-mail: razanov@vsau.vin. ua).

Posternak Leonid Ivanovich – Candidate of Agricultural Sciences, Associate Professor of the department of technology of production of livestock products of the faculty of technology of production and processing of livestock products Vinnytsia National Agrarian University (21008, Vinnytsia, Sonaychna St., 3, e-mail: agronomy@vsau.vin.ua).

Khomyakovsky Yuriy ludwigovich – Senior Lecturer of the department of mathematics, physics and computer technologies of the faculty of economics and entrepreneurship of Vinnytsia National Agrarian University, (21008, Vinnytsia, Sonaychna St., 3).

The specific activity of cesium-137 in the muscle tissue of pond and river fish, grown in the conditions of intensified radiation control of Vinnytsia region, was studied. The obtained results of the studies indicate a low specific activity of cesium-137, which does not exceed the maximum permissible levels (SR-2006). The certain regularities of accumulation of cesium-137 in the muscle tissue of fish depending on their species and conditions of existence are revealed. In particular, the specific activity of cesium-137 in the muscle tissue of Silver crucian, grown in ponds, was by 59.7%, of roach by 67.2%, of perch by 51.1%, of pike by 64.6% and of Scaly carp by 70% higher compared to the similar fish grown in rivers. The predatory fish (perch, pike) were characterized by the highest specific activity of cesium-137, while that one of the herbivorous fish (Silver carp) was relatively lower.
