Examination conducted in 1987--1988 included 200 samples of the autopsy material of subjects who died of various causes in different regions of Byelorussia. It revealed the presence of "hot" particles (i.e. particles with high specific radioactivity) in 50% of the samples taken from the northwest and in 70% of those from the southeast regions. A correlation was found to exist between the radioactive particles content in the soil, air and lungs of residents from the contaminated territory. It was shown that in 1990--1991, in contrast to 1987--1988, the particles content in a single lung sample reduced, which was associated both with mechanical removal of particles and their disintegration and, as a consequence with the accumulation of plutonium in the body. Study of radioactive particles distribution in the whole lung showed that at present they are found primarily in the lower segments.
1987 - 1988年进行的检查包括从白俄罗斯不同地区因各种原因死亡的受试者身上采集的200份尸检材料样本。结果显示，从西北部采集的样本中有50%存在“热”粒子（即具有高比放射性的粒子），而从东南部地区采集的样本中有70%存在此类粒子。研究发现，受污染地区居民土壤、空气和肺部中的放射性粒子含量之间存在相关性。结果表明，与1987 - 1988年相比，1990 - 1991年单个肺部样本中的粒子含量有所减少，这既与粒子的机械清除及其衰变有关，也与钚在体内的积累有关。对整个肺部放射性粒子分布的研究表明，目前它们主要存在于肺下部。
