| Abstract: | After the Chernobyl event, the problem of contamination of natural and semi-natural ecosystems has been particularly salient even where these nonagricultural land areas appear to generate only a small fraction of the annual food intakes of certain populations. A concise discussion of some features of natural ecosystems is presented here, with the objective of stimulating a closer inspection of the relative impact of these natural ecosystems on the eventual dose to man. The ability of natural systems to scavenge considerable amounts of contamination is emphasized and it is suggested that there is a need for further work to quantify the importance of these environments, relative to agricultural systems, in terms of producing eventual transfers to man. |
