Studies on the influence of high levels of radiation on soil fauna were carried out in 2012 in the territory formed as a result of the activity of the enterprise for extraction and production of radium from reservoir water and waste of uranium ore from 1931 to 1956. At present the local radioactive pollution in this area is caused by the presence of heavy natural radionuclides 226Ra, 238U and products of their disintegration in soils. The oppression of soil invertebrate.fauna in pine forests and meadows with high levels of radionuclides and heavy metals is revealed. Also shown is the decrease in the number and density of different taxonomic groups of invertebrates, reduction of the diversity and spectrum of trophic groups and vital forms in the area with a high content of radionuclides in soil. Our results are in agreement with the results obtained by the similar studies showing negative influence of high-level ionizing radiation on soil fauna.
2012年，在1931年至1956年从水库水和铀矿废料中提取和生产镭的企业活动所形成的区域内，开展了关于高剂量辐射对土壤动物群影响的研究。目前，该地区的局部放射性污染是由土壤中存在重天然放射性核素226Ra、238U及其衰变产物造成的。研究揭示了放射性核素和重金属含量高的松林和草甸中土壤无脊椎动物群受到的抑制。研究还表明，土壤中放射性核素含量高的区域内，不同分类群的无脊椎动物数量和密度减少，营养类群和生命形式的多样性及范围降低。我们的研究结果与类似研究所得结果一致，这些研究表明高剂量电离辐射对土壤动物群有负面影响。
