After the analysis of the obtained results for the first time it is revealed that the above-stated strains of micromycetes transfer 241Am from the bound form in the solid-fuel particles, to biological available forms. At the same time during of growthing of the strains there was not the considerable activity of 241Am nuclei in a nutrient solution which remains after carrying out of the experiment. The control experiment in which only both nutrient solution and "hot" particles was used at the same duration of the experiment as first case with two strains of micromycetes also did not observe the considerable activity of 241Am. It is revealed that accumulation of 241Am in these strains is much higher than accumulation of 137Cs. Activity 137Cs twice passes into soluble forms in comparison with assimilation by fruit bodies. It indicates presence of a radiotropism for strains of the C.cladosporium micromycetes. Fruit bodies at which there is a ground mass of the acquired 241Am become biological accessible to the subsequent inclusion of 241Am in a line-up a soil - a plant. The anticorrelation of assimilation of 241Am is observed with the mass of uranium which is in fuel particles. Expected hypotheses concerning development of an object of a research - are to disclosure of a role of the mycorrhizal fungi fungi in root receipt of the technogenic radionuclide. It will allow developing new approaches to the organization of protective measures in crop production and on the territories, which are polluted of radionuclide.
