本文报道了1976～1981年间按全国平均的苏联主要食品、膳食、居民体内器官中~(90)Sr和~(137)Cs的含量以及居民的受照水平。在此期间分析了食品样约37000份、取自52个城市人数超过150,000人的骨组织和牙齿样约4200份。采用B.A.等发表的放化分析、测量和数据处理方法。按照苏联食品污染和居民营养构成的资料计算确定~(90)Sr和~(137)Cs随膳食的摄入量和体内~(137)Cs的含量。鉴于~(137)Cs核素在体内的
This paper reports the content of ~ (90) Sr and ~ (137) Cs and the exposure level of residents in the organs, the main food, meals and residents in the Soviet Union from 1976 to 1981 according to the national average. During this period, about 37,000 food samples were analyzed, taking about 4,200 bone tissue and dental samples from over 150,000 people in 52 cities. B.A. and other published radiochemical analysis, measurement and data processing methods. According to the data of food contamination and resident nutrition in the Soviet Union, the intake of dietary (~ (90) Sr and (137) Cs and the content of 137 Cs in the body were calculated and calculated. Given the ~ (137) Cs nuclide in vivo
