A model system which permits observing for a long time and fixing interaction of fungi with a radiation source has been created on the basis of an isolated "hot" particle, deficient mineral medium (saccharose content 60 mg/l) and suspension of fungal conidia. Five species (six strains) of micromycetes isolated from radionuclide-contaminated soils and fifteen "hot" particles have been tested. It has been found out for the first time that Cladosporium cladosporioides and Penicillium roseo-purpureum are able actively overgrow "hot" particles whose radioactivity did not exceed 3.1-1.0(-7) Ci by gamma-spectrum and to destroy them 50-150 days later. Certain changes in morphology of fungi-destructors of "hot" particles are revealed. A problem on ecological significance of the found phenomenon is discussed.
基于分离出的“热”粒子、缺乏矿物质的培养基（蔗糖含量60毫克/升）和真菌分生孢子悬浮液，构建了一个能够长时间观察并确定真菌与辐射源相互作用的模型系统。对从受放射性核素污染土壤中分离出的5种（6个菌株）微真菌和15个“热”粒子进行了测试。首次发现，枝孢菌和玫瑰紫青霉能够积极覆盖放射性通过伽马能谱不超过3.1 - 1.0（-7）居里的“热”粒子，并在50 - 150天后将其破坏。揭示了“热”粒子破坏真菌的形态发生的某些变化。讨论了所发现现象的生态意义问题。
