RADIATION AND HYGIENIC ASSESSMENT OF CONTENT AND DISTRIBUTION OF CESIUM-137 IN DIFFERENT TAJIKISTAN AREAS

Abstract

The study have been conducted on cesium-137 content in the soil layer of various Tajikistan regions, covering an area of about 45,000 km2. The dependence of cesium-137 accumulation on the studied regions terrain relief has been established. The dynamics of cesium-137 distribution in the soils of not cultivated and cultivated fields in Tajikistan has been investigated. It has been found that cesium-137 isotope content in the cultivated fields differs from the not cultivated ones. At the mountain pedestal areas and clayey soils, there is a relatively high cesium-137 isotope content compared to the plain areas.
