210Po and 210Pb Isotopes Content in the Water of Artificial Lake of Istiklol City of the Republic of Tajikistan and their Bioaccumulation in the Fish

Abstract

The results of monitoring of 210Po and 210Pb isotopes in water of artificial lake (former uranium mine) of Istiklol city of the Republic of Tajikistan and their bio-accumulation are given. Fish living in this area is using as a food by local population. It has been found that the level of210Po isotope in the liver of fish, in particular of carаs fish, was relatively high. It has been defined that the annual effective radiation dose from gamma radiation and isotopic activity in water for human in the Istiklolcity exceeds the recommended annual threshold dose level (10 mSv).
