为了确定切尔诺贝利事故后目前的内辐射暴露风险，从1998年到2008年对俄罗斯联邦布赖恩斯克市居民的Cs-137身体负担进行了评估。研究人群由84666人组成，他们去布赖恩斯克第二医院就诊。用全身计数器测量~(137)Cs负荷量。CS-137浓度在研究后期明显偏高，并呈现季节性变化，表明居民可能食用了受污染的林产品。然而，在研究的所有年份，年暴露剂量较高的人都相当罕见。总而言之，尽管布赖恩斯克市的Cs-137内辐射暴露持续到今天，但几乎所有居民的年暴露剂量都很低。由于Cs-137的半衰期很长，有必要进行长期跟踪，以监测切尔诺贝利周围居民的健康状况，缓解他们的焦虑。
To determine the current risk of internal radiation exposure after the Chernobyl accident, the Cs-137 body burden of the inhabitants of Bryansk Oblast, Russian Federation was evaluated, from 1998 to 2008. The study population is composed of 84 666 people who visited Bryansk No. 2 Hospital. A whole-body counter was used for measurement of Cs-137 body burden. Cs-137 concentration was significantly higher in the late period during the study and showed seasonal variation, suggesting that inhabitants may have consumed contaminated forest products. However, people with high annual exposure doses were quite rare during all years of the study. In conclusion, although internal radiation exposure from Cs-137 continues to this day in Bryansk Oblast, the annual exposure dose is low in almost all inhabitants. Because of the long half-life of Cs-137, the long-term follow-up is necessary to monitor the health status and relieve the anxiety of the inhabitants around Chernobyl.
