Of the 500,000 immigrants from the former Soviet Union who came to Israel during 1990-1993, about 100,000 are estimated to have come from radiocontaminated areas near Chernobyl. These people were subject to chronic uptake of environmental radiocesium over protracted periods. During October-November 1991, a joint Israeli-Canadian investigation measured radiocesium body burdens in immigrants to Israel from the Ukraine, Belarus, and the southern Russian republic in order to provide factual information on radiocesium levels to concerned immigrants and to relate the body burdens to the geographic area of residence before coming to Israel. Assessments were made of 137Cs body burdens in 1,228 volunteer men, women, and children. These measurements were accompanied by medical assessments based on clinical histories and examinations. Radiocesium levels were strongly dependent on the duration of residence in Israel, with the highest levels being found in the most recent immigrants. The maximum level, extrapolated back to the time of leaving the former Soviet Union, was estimated to be about 0.83 kBq (10.3 Bq kg-1). Of the most recent immigrants from the Kiev region (< 101 days in Israel), only 15% had back extrapolated body burdens > 50 Bq, whereas 53% of those coming from Gomel and other towns in the contaminated zones (> 3.7 x 10(10) Bq km-2 of radiocesium) had detectable levels > 50 Bq. People coming from the latter region had significantly higher body burdens as compared to those from the former, in accordance with the higher degree of ground radiocesium contamination reported for the latter region. Women and children showed considerably lower total radiocesium content in comparison to men. All radiocesium body burdens at the time of measurement were too low to be of health concern.
在1990年至1993年期间来到以色列的50万前苏联移民中，估计约有10万人来自切尔诺贝利附近的放射性污染地区。这些人长期受到环境放射性铯的慢性摄取。1991年10月至11月，以色列和加拿大联合进行了一项调查，测量了来自乌克兰、白俄罗斯和俄罗斯南部共和国的以色列移民体内的放射性铯负荷，以便向相关移民提供有关放射性铯水平的实际信息，并将体内负荷与来以色列之前的居住地理区域联系起来。对1228名志愿者男性、女性和儿童的137Cs体内负荷进行了评估。这些测量还伴随着基于临床病史和检查的医学评估。放射性铯水平强烈依赖于在以色列的居住时间，最新移民中的水平最高。推算回离开前苏联时的最高水平估计约为0.83 kBq（10.3 Bq kg-1）。来自基辅地区的最新移民（在以色列<101天）中，只有15%的人推算后的体内负荷>50 Bq，而来自戈梅利和污染区其他城镇（放射性铯>3.7 x 10(10) Bq km-2）的移民中，53%的人可检测水平>50 Bq。与来自前一地区的人相比，来自后一地区的人的体内负荷明显更高，这与后一地区报告的地面放射性铯污染程度较高一致。与男性相比，女性和儿童的总放射性铯含量要低得多。测量时所有放射性铯体内负荷都太低，不会对健康造成影响。
