“…These measures, when taken during the few first weeks after the accident, resulted in a substantial reduction of the doses, especially in the thyroid doses to children (27,51) . Later, countermeasures were also effective in reducing internal exposure from radiocaesium ingestion (12,46,78,79) .…”

On the occasion of the 20th anniversary of the Chernobyl accident an attempt has been made to evaluate the impact of the Chernobyl accident on the global burden of human cancer in Europe. This required the estimation of radiation doses in each of the 40 European countries. Dose estimation was based on the analysis and compilation of data either published in the scientific literature or provided by local experts. Considerable variability has been observed in exposure levels among the European populations. The average individual doses to the thyroid from the intake of 131 I for children aged 1 y were found to vary from $0.01 mGy in Portugal up to 750 mGy in Gomel Oblast (Belarus). Thyroid doses to adults were consistently lower than the doses received by young children. The average individual effective doses from external exposure and ingestion of long-lived radiocaesium accrued in the period 1986-2005 varied from $0 in Portugal to $10 mSv in Gomel Oblast (Belarus) and Bryansk Oblast (Russia). The uncertainties in the dose estimates were subjectively estimated on the basis of the availability and reliability of the radiation data that were used for dose reconstruction in each country.

“…While the half-life of 137 Cs in agricultural products is 2.8–5.6 years, it is approximately 10 years for berries and 20 years for mushrooms [11]. Fesenko, et al[12] studied twenty-seven rural settlements to assess the effectiveness of countermeasures. They observed an initial decrease of up to 40% of doses with a gradual diminution of effect over time.…”

“…First, there have been observations34 that, in forest ecosystems, 137 Cs deposited by the Chernobyl NPP accident has still been observed in topsoils (including the litter layer or O horizon) and has become a major potential source for soil-to-plant transfer for the long term. There are very few countermeasures to effectively reduce the cycling of 137 Cs in the forest ecosystems5. Therefore, long-term external and internal (through consumption of food products from 137 Cs-contaminated forests) radiation exposure in the affected areas such as the Fukushima NPP area is possible.…”

The fate of 137Cs derived from the Fukushima nuclear accident fallout and associated radiological hazards are largely dependent on its mobility in the surface soils of forest ecosystems. Thus, we quantified microbial and adsorptive retentions of 137Cs in forest surface (0–3 cm) soils. The K2SO4 extraction process liberated 2.1%–12.8% of the total 137Cs from the soils. Two soils with a higher content of clay- and silt-sized particles, organic carbon content, and cation exchange capacity showed higher 137Cs extractability. Microbial biomass was observed in all of the soils. However, the 137Cs extractability did not increase after destruction of the microbial biomass by chloroform fumigation, providing no evidence for microbial retention of the Fukushima-fallout 137Cs. The results indicate that uptake of 137Cs by soil microorganisms is less important for retention of potentially mobile 137Cs in the forest surface soils compared to ion-exchange adsorption on non-specific sites provided by abiotic components.
