Abstract

The results of the analysis of the radiation state of environmental objects in the sanitary protection zone (SPZ) and surveillance zone (SZ) of the research nuclear reactor (RNR) WWR-M of the Institute for Nuclear Research of the National Academy of Sciences of Ukraine (INR) for 2021 are analyzed and compared with the data for previous years (from 2016 to 2020). The levels of total beta activity of sedimentary dust and atmospheric precipitation and wastewater from the main reservoirs of INR, the concentration of beta-active aerosols in the surface layer of atmospheric air, as well as the content of 137Cs radionuclide in soil and vegetation samples, were studied. The research was conducted in the laboratory of the Center for Ecological Problems of Atomic Energy of INR. The obtained results show that in 2021 there was no excess of the values of controlled parameters compared to previous years. There was also no significant difference in the specific activity of the radionuclide 137Cs in soil and vegetation samples from SPZ and ZS. Studies conducted in the period from 2016 to 2021, allowed to accumulate significant factual material on the radiation situation in the sanitary protection zone and surveillance zone and to substantiate the conclusion about the absence of man-made radioactive contamination of the environment due to the operation of RNR WWR-M of INR of NAS of Ukraine.

乌克兰国家科学院核研究所2021年核研究堆卫生防护区和观测区辐射状况分析

对乌克兰国家科学院核研究所(INR)研究堆(RNR) WWR-M的卫生防护区(SPZ)和监视区(SZ)环境物体的辐射状态分析结果进行了分析，并与前几年(2016年至2020年)的数据进行了比较。研究了沉积尘埃、大气降水和INR主要水库废水中总β活性水平、大气表层β活性气溶胶浓度以及土壤和植被样品中137Cs放射性核素含量。这项研究是在INR原子能生态问题中心的实验室进行的。得到的结果表明，2021年的控制参数值与往年相比没有超出。在土壤和植被样品中，放射性核素137Cs的比活度也没有显著差异。在2016年至2021年期间进行的研究，可以积累有关卫生保护区和监测区辐射情况的重要事实材料，并证实乌克兰NAS INR的RNR WWR-M运行没有人为的环境放射性污染的结论。
