ОПРЕДЕЛЕНИЕ ВКЛАДА 3Н В ДОЗОВУЮ НАГРУЗКУ ДЛЯ ПЕРСОНАЛА И НАСЕЛЕНИЯ ПРИ ЕГО ПОСТУПЛЕНИИ С ВОЗДУХОМ НА ТЕРРИТОРИИ СЕМИПАЛАТИНСКОГО ИСПЫТАТЕЛЬНОГО ПОЛИГОНА

The paper provides tritium (3Н) concentrations in atmospheric air in the venues of tunnels at the «Degelen» testing site of Semipalatinsk Test Site (the STS). Tritiated water (НТО) and gaseous tritium compounds (НТ) in air environment were registered in air environment both at the «Degelen» testing site and beyond its boundaries. Based on the data obtained, contribution of 3Н entering with air into radiation exposure of personnel and population was determined through the example of the «Degelen» testing site. It was found, that contribution of 3Н to radiation exposure of the personnel (inhalational intake), carrying out works in the venues with the maximum concentration of 3Н in the air does not exceed 1%. Contribution of 3Н to the radiation exposure of population, performing economic activities beyond the «Degelen» site, in the venues of streamflows with high concentration of 3Н in water and in air will be approximately 10%.
