 note = {About 60 major and trace elements as well as radiocesium in environmental samples were determined in order to obtain basic information for environmental radiation protection and ecotoxicology. Levels and distribution in plants, mushrooms and soils collected in forest ecosystems were discussed. Data of radiocesium and related stable elements indicated that the high 137Cs, Cs and Rb concentrations and low Ca and Sr concentrations, in comparison with plants, could characterize mushroom composition. Relationships between radiocesium and stable Cs in mushrooms and plants were discussed. The results indicated that the ratio between radiocesium and stable Cs is useful for judging the equilibrium of deposited radiocesium in different components comprising a forest ecosystem. The stable Cs analyses might be also useful to predict the long-term radiocesium contamination of mushrooms and plants. Transfers of the elements from media to earthworms, and distribution of the elements in an aquatic microcosm were also discussed., International Conference on the Protection of the Environment from the Effect of Ionizing Radiation},
