Diffusion and transport of radiocesium down the soil-plant-deer pathway in two different forests chosen as ecosystems

During the period from 1987 until 1991, the diffusion and transport of Cs-137 down the soil-plant-deer pathway was examined on the basis of spatial and temporal factors for two different ecosystems. Using data taken from the relevant literature a survey is provided of the behaviour of radiocesium in the soil, plants and mammalian organism. This is followed by a retrospective evaluation of the contamination of the environment with radiocesium that was caused during the fifties and sixties by above-ground tests with nuclear weapons. The distribution of fallout radionuclides after the Chernobyl reactor accident is dealt with subsequently. (orig.)
