Abstract  

The dynamics of the radiation situation in the Republic of Belarus is presented. The contamination of the territory of Belarus for different radionuclides is given for example: iodine-131, caesium-137 strontium-90 and plutonium isotopes. The dynamics of the contamination of caesium-137, in the surface water of the rivers of Belarus is shown. At present, the radiation situation of the territory of Belarus has stabilized, however, the result of the monitoring shows that in the soil and objects of the environment the accumulation of americium-241 is observed and in course of time its concentration will increase. Forecast of distribution of caesium-137 on the territory of Belarus shows that the contamination of more than 37 kBq·m−2 will be observed in 2016 at the area more than 28300 km2. That account 14% from the total territory of Belarus.

Abstract  

A vertical migration of radionuclides Cs, Sr and Pu in soils (in upper 5 cm) of Belarus is given. Influence of genetic parameters of soil for vertical migration of radionuclides is introduced. The main factor of the velocity for radionuclides migration is super humidity. A forecast of vertical migration of radionuclides is made for the year 2016.
