Abstract

Radionuclide release to environment is possible during long-term storage of the low and middle activity radioactive waste on specially equipped territories, which leads to radioactive background increase and to permanent radiation influence to biocenosis. For an ecological situation control in such places it is need to provide a biomonitoring using the method of complex estimation of the morphological changes on whole organism and internal organs levels (presents of tumors, teratogenic effects), the hematological indexes reflected quantifies and qualifies changes in blood, cytogenetic distribution (bone marrow polychromatic erythrocytes with micronuclei) and distributions on molecular level (alterations of DNA structure lead to increase in the DPC level).

摘要

在配备特殊设施的区域长期储存中低放射性废物期间,放射性核素可能释放到环境中,这会导致放射性本底增加,并对生物群落产生永久性辐射影响。为了控制这些地方的生态状况,需要采用对整个生物体和内部器官水平的形态变化进行综合评估的方法(肿瘤的存在、致畸效应)进行生物监测,血液学指标反映血液中的定量和定性变化,细胞遗传学分布(含微核的骨髓多染红细胞)以及分子水平的分布(DNA结构改变导致DNA-蛋白质交联水平升高)。
