Radiological condition of farmland in Ukrainian Polissya

The accident at the Chornobyl nuclear power station caused a radioactive pollution in 1986. The size of distribution of radioisotopes is considered to be a global catastrophe. Due to the escalation of radioactive clouds and characteristic peculiarities of climate and soil typical for biogeocenose of Polissia, the examination of soil of agricultural lands resulted in concluding that the most contaminated regions are Chernihiv, Kyiv, Zhytomyr, Rivne, and Volyn regions. The analysis of the density of soil contamination with 137Cs and 90Sr which has been done through radiological monitoring for thirty years after the Chornobyl accident is currently important due to the fact that the half reduction of radio isotopes usually takes such a period of time. Therefore, this article presents agricultural land areas of contaminated soils 137Cs during the 1986; it also considers their current radiological state. It should be noted that a statement of purpose to conduct specifying radio ecological examination of land is done to get an intrinsic evaluation of changes in the density of contaminated soils of agricultural land areas.
