Radioactivity - a subject of spatial research

From the scientific point of view, the evaluation of the long-term consequences of the Chernobyl reactor accident still is a matter of discussion. Particularly questions such as a possible accumulation of pollutants and the resulting impact on susceptible land use, or the genetic effects in the long run of the low-dose radiation exposure count among the problems that still need clarification. There is demand for an areawide mapping of radiation doses according to one standard method, so as to establish a basis for a large-scale field study. (orig.)
