[Current Activity Levels of Artificial Radionuclides in Water Facilities Located at the Semipalatinsk Test Site].

The current data of radioecological research within the Semipalatinsk test site (STS) are presented in the pa- per. It has been shown that almost 90% of polygon lands can be returned to the national economy. Waters of water facilities located at conditionally "background" territories of the STS do not present a radiation hazard to population. Waters of the potential water facilities located close to the radiation hazardous facilities have an increased level of the specific activity of individual radionuclides. Recommendations for the radiological assessment of the quality of waters in water facilities located near radiation hazardous facilities and adjacent territories of STS are offered in the article.
