Comparison assessment of the potential radiation hazard of tailing dumps in the Sughd region of Tajikistan

The global environmental changes have been observed since the nineties of twentieth centu-ry. current situation is caused mainly due to intensive human activity. Dur-ing 46 years, from 1945 1991, radioactive waste uranium processing was accumulated in Sughd region Tajikistan, former USSR Republic. According various estimates to-tal amount radioactivity varies 240 285 TBq. tailings are major sources pollution, they contain emanating gas, aerosols, dust and filterable solutions. purpose work conduct comparison assessment potential radiation hazard “Digmai” “Adrasman” tailing dumps Istiklol-city estimate radiological risks population living near dumps. For radon monitoring both integral instantaneous measurements were used. instant volu-metric activity PPA-01M-03 LLC “HTM-Protection” (Russia) raidometer back-ground area under study measured with Dosimeters DKS-96 “Dose” (Rus-sia), DKS-AT1123 “Atomtech” (Belarus), MKS-AT6130 (Belarus) PackEye FHT complex-1377 “Thermo” (Germany). paper presents data on po-tential area. impact radioecological region, as well cities districts assessed. most unfavorable areas ambient dose equivalent power (MAED)>0.35-0.40 μSv/h. coordinates location coincide Gaziyeon (“Digmai”) location, their adjacent territories. assessment, “Factory Poor Ores” (Istiklol-city) potentially haz-ardous facilities. It means that for safety environment population, it recommended carry out cleaning remediation a priority: «Dig-mai» «Factory poor ores».
