Radiation accidents, regular activities of nuclear power cycle enterprises, and nuclear weapons testing are sources of artificial high radiotoxicity actinides entering the environment. The actinides' long half-lives result in their constant accumulation on a planetary scale. Radioactive microparticles are one of the common forms of artificial actinides in soils. According to recent studies, soil micromycetes can increase the processes of hot particles destruction. A presented paper shows the ability of Cladosporium cladosporioides to transfer 241Am from hot particles containing 241Am and 137Cs to the mobile biologically available form. We observed the 241Am direct accumulation by micromycete mycelium for the first time. In contrast, the interaction of studied strains with 137Cs from hot particles was different.
