从1991年到1998年，来自俄罗斯和瑞典的工作人员进行了测量，以估计布良斯克地区一些村庄居民的内照射量，这些村庄在1986年切尔诺贝利核电站事故后受到了严重的Cs-134和Cs-137污染。人体放射性核素含量的测量采用两种技术：全身计数法和基于尿样中Cs-137和肌酐浓度测量的间接方法。测量结果表明，农村居民中~（134）Cs和~（137）Cs含量受自然因素和社会因素的影响。儿童体内铯放射性核素含量随年龄增长而增加，成人体内达到最大值。男性全身铯-134和137的平均含量比女性高1.7倍。选择性测量铯放射性核素的方法用于集体尿样中群体平均全身含量的估计是成功的。
From 1991 to 1998, workers from Russia and Sweden performed measurements to estimate the internal exposure of the inhabitants in some villages of the Bryansk region which were severely contaminated with Cs-134 and Cs-137 after the Chernobyl Nuclear Power Plant accident in 1986. The measurements of the radionuclide content in the human bodies were performed with two techniques: whole-body counting and an indirect method based on measurement of Cs-137 and creatinine concentration in urine samples. The measurement results have shown that Cs-134 and Cs-137 content in rural inhabitants depends both on natural and social factors. It is also shown that caesium radionuclides content in children increases with age and reaches the maximum values in adults. Mean whole body content of Cs-134 and Cs-137 in men higher by a factor of 1.7 than in women. The method of selective measurement of caesium radionuclides applied for estimation of average whole body content in groups concentration in collective urine samples may be successfully of persons.
