Title: Estimation of the ratio of 90Sr and 137Cs activities in the Chernobyl depositions in the territory of the Russian Federation

Author: Ermilov A.P., Ziborov A.M.

Reference: Journal: Radiation and Risk (Bulletin of the National Radiation and Epidemiological Registry), Year: 2001 Issue: 12

Keywords: contamination, cesium-137, strontium-90

Abstract: Correlative relationship between activities of 90Sr to 137Cs in condenses of the Chernobyl fallouts on April 26, 1986 was detected. The ratio was estimated with the use of data of the Institute of Global Climate and Ecology of the State Committee of Hydrometeorology and Russian Academy of Sciences. The data derived from measurements of 90Sr, 137Cs and 239+240Pu in soil samples taken in Bryansk, Kaluga, Oriol and Ryazan regions in 1992. The contribution of the condensation of 90Sr in the soil samples of the Chernobyl fallout in Russia was found to be governing factor when specific activity of 137Cs was > 2000 Bq/kg.

Title: Radioecological situation in the forest ecosystems of the Ryazan region, contaminated as a result of the accident at the Chernobyl nuclear power plant

Author: Kononova, Galina Alexandrovna

Reference: Moscow, 2004

Keywords: Ryazan region, forest vegetation, radionuclide migration, cesium-137, ecosystem, mushrooms

Abstract: The main purpose of the work was to study the radiological situation in the forest ecosystems of the Ryazan region contaminated by radionuclides due to the accident at the Chernobyl nuclear power plant, to determine the levels of cesium in the timber and non-timber forest resources, to assess their compliance with sanitary and hygienic regulations.
