There has been an extraordinary increase in interest concerning the transfer of radioactive contamination to the fruit bodies of fungi since the Chernobyl nuclear power plant accident. These investigations, however, have focused exclusively on field studies aimed fundamentally at quantifying the behaviour of the radiocaesium component of the contamination. The results have shown great variability. As a contribution towards this body of knowledge, we have made a comparative study of the temporal evolution of the transfer of 85Sr and 134Cs via three routes of radioactive contamination--from the mycelium, from the surface layer of the soil, and directly onto the caps of the fruit bodies--for the saprophyte species, Pleurotus eryngii, under controlled laboratory conditions. The results indicate that the last of the above three uptake routes is the most efficient, and that the temporal evolution of the transfer is closely related to the radionuclide and the radioactive contamination route being considered.
自切尔诺贝利核电站事故以来，人们对放射性污染物向真菌子实体转移的关注度急剧上升。然而，这些研究仅集中在实地研究上，其根本目的是量化污染物中放射性铯成分的行为。结果显示出很大的变异性。作为对这一知识体系的贡献，我们在可控的实验室条件下，对腐生菌杏鲍菇通过三种放射性污染途径（从菌丝体、从土壤表层以及直接到子实体菌盖）转移85Sr和134Cs的时间演变进行了比较研究。结果表明，上述三种吸收途径中最后一种最为有效，并且转移的时间演变与所考虑的放射性核素和放射性污染途径密切相关。
