The present work is devoted to an analysis of the data on the dynamics
of Cs-137 transfer factors in the current most critical (for the popu
lation of Russia) links of food chain: 'soil mushrooms' and 'soil berr
ies'. Data were obtained during 1986-1994 in the most contaminated reg
ion of Russia - the Bryansk region - and then were used for assessing
the contribution of forest products consumed by the population of cont
aminated territories to internal exposure doses. It was shown in contr
ast to agricultural food products (where natural decontamination took
place quickly) that radioactive decontamination of mushrooms and berri
es during the eight years after the Chernobyl accident was very slow.
Use is made of aggregated radioecological data together with broad ass
umptions about the consumption of forest products to predict the doses
that might arise from consumption of such foodstuffs. These predictio
ns are then compared with values derived from whole-body measurements.
