The Role of the Forest Products in the Formation of Internal Exposure Doses to the Population of Russia after the Chernobyl Accident

Long-term stability of decontamination effect in recreational areas near the town Novozybkov, Bryansk Region, Russia

“…Nevertheless, the very great decontamination effect for edible fungi observed in this study may be a beneficial factor with respect to the reduction in the total effective dose to the visitors of recreational areas. At present, the consumption of forest mushrooms is a considerable source of human internal exposure in the Bryansk Region (Shutov et al, 1996;Bruk et al, 1999;Travnikova et al, 2001).…”

Soil-dependent uptake of 137Cs by mushrooms: experimental study in the Chernobyl accident areas

“…This has been attributed to both the longterm retention of radiocaesium in forest litter and organic soil layer, in a form that is highly mobile and available for fungal mycelium (Sugiyama et al, 1994), and the specific biochemical feature of fungal tissues, and specifically their fruit bodies, to accumulate and concentrate microscopic quantities of caesium (Vinichuk, 2003). Furthermore, for some mushroom species an increase of 137 Cs specific activity in the first 1e2 years after the accident has been observed (Shutov et al, 1996;Bruk et al, 1999). This might be explained by the fact that radiocaesium often migrates from the upper forest floor to the layer of mushroom mycelium within this observation time period.…”

“…(1) and (2). Thus, for sensible prediction of 137 Cs transfer coefficients from forest soil to different mushroom species and further estimation of radionuclide intake of local residents and associated internal dose (Shutov et al, 1996Bruk et al, 1998Bruk et al, , 1999Recommendations, 2003) relatively little information is needed, i.e., clay content (%) and soil acidity (pH). This information is usually available in the Russian Forestry Service branches.…”

Characteristics and Prognosis of the Internal Exposure Doses of the Ukrainian Polissya Rural Population in the Remote Period After the Accident at the Chernobyl Nuclear Power Plant (Monitoring Study)

“…Саме ці продукти харчування накопичують 137 Сs, якому належить май же 3/4 у структурі дозового навантаження на насе лення внаслідок аварії на ЧАЕС [4,5]. Їх внесок у до зу внутрішнього опромінення коливається від 12 до 40 % у всього населення Полісся і до 50-95% -у йо го критичних груп [6][7][8]. Все вищезазначене й виз начило мету нашого дослідження.…”

“…These particular food products accumulate 137 Cs, which takes almost 3/4 in the dose structure of the population caused by the ChNPP accident [4,5]. Their contribution to the internal exposure dose ranges from 12 to 40 % for the total Polissya popu lation to 50-95 % for its critical groups [6][7][8]. All the above determined the goal of our research.…”
