The authors represent summarized data on the time course of incorporated Cs in the population of the Krasnogorsk District of Bryansk Province over the period of June 1986-July 1989. A RIKh-5M device used as a counter of human radiations, its technical data and calibration methods were described. A retrospective analysis has shown that the main accumulation of radionuclides occurred before May 15 1986. The highest rates of Cs clearance from the body were noted in the period of August 1986 till February 1987, the average resultant periods of semiclearance for different populated areas and groups of population were 55-85 days. The ratio of accumulated Cs in children and adults was 0.3, in men and women--1.4. The effectiveness of measures aimed at reducing collective doses of internal irradiation was analyzed.
作者展示了1986年6月至1989年7月期间布良斯克州克拉斯诺戈尔斯克区居民体内铯摄入时间进程的汇总数据。描述了用作人体辐射计数器的RIKh - 5M装置、其技术数据和校准方法。回顾性分析表明，放射性核素的主要积累发生在1986年5月15日之前。1986年8月至1987年2月期间观察到人体铯清除率最高，不同人口聚居区和人群的平均半清除期为55 - 85天。儿童与成人积累铯的比例为0.3，男性与女性的比例为1.4。分析了旨在降低内照射集体剂量措施的有效性。
