Abstract/Summary

An assessment of the distribution of Chernobyl fallout in a Swedish forest was carried out and showed more than 95% of the in the system to be of Chernobyl origin. The data show that approximately 87% of total fallout is found in soils, 6% in the bryophyte layer and 7% in standing biomass of trees. The mean deposition of in the system (including soils, bryophytes, understorey vegetation, fungi, trees, moose and roe deer) was 54 kBq m−2. Fungi, understorey vegetation and ruminant populations collectively contained approximately 1% of total radiocaesium in the system. However, actual concentrations in these sample types were higher than in any other category, mostly exceeding the limit of 1500 Bq kg−1 for consumption of wild produce in Sweden. These categories represent the principal foodstuffs responsible for radiation transfer to man from the system and though negligible in total biomass there is potential for significant dose transfer to individuals who are regular consumers of wild forest produce.
