Description
Results of experimental and theoretical investigations into behavior of 32P in the Yenisei river being admitted more 30 years with effluents of the Krasnoyarsk Mining-Chemical Plant are performed. It is shown that 32P is actively accumulated by water organisms, among other factors, its concentration in fish is thousand times higher than its concentration in water. Content of 32P in fish depends on the season of year accomplishing maximum value in August. Model of dynamics of thr 32P contamination of fishes of the Yenisei river during 25-year period of work of the Plant was developed and verified. Radiation dose of fisherman and members of their families through 32P ranged 0.4-1.6 mSv/year in 1975-1992. For rural population radiation dose from 32P was in the ranges of 0.14-0.5 mSv/year at the same time
Abstract (Russian)
Представлены результаты экспериментальных и теоретических исследований поведения в Енисее 32P, поступавшего более 30 лет со сбросами Красноярского горно-химического комбината. Показано, что 32P активно аккумулировался водными организмами, в частности, его концентрация в рыбе в тысячи раз превосходила концентрацию в воде. Содержание 32P в рыбе зависит от сезона года, достигая максимального значения в августе. Разработана и верифицирована модель динамики загрязнения 32P рыб Енисея за 25-летний период работы комбината. Доза облучения рыбаков и членов их семей за счет 32P составляла в 1975-1992 г.г. 0.4-1.6 мЗв/год. Для сельского населения доза облучения от 32P в те же годы находилась в пределах 0.14-0.5 мЗв/годAdditional details
