COMPOSITION AND PROPERTIES OF RADIOACTIVE PARTICLES DETECTED IN THE SOUTHERN DISTRICTS OF BYELARUS

Composition and properties of ''hot particles'' found in registration points of landscape-geochemical testing areas within 40-250 km off Che rnobyl NPP have been studied by means of gamma-spectroscopy, beta-radi ometry, radiochemistry, X-ray and fluorescent analysis. A study of rad ioactive particles distribution was conducted for soil and atmosphere of Southern regions of Belarus'. The data on prevalence of radioactive particles over the territory and as a function of depth of soil secti ons of control regions were obtained. Radionuclides and ''hot particle s'' distributions as a function of granulometric composition of soil w ere studied. It has been shown that the total picture of distribution of radioactive particles in Southern regions of Belarus' was unchanged during years.
