Title: Content of Radionuclides of Chernobyl Origin in Food Products for the Belarusian Population
Author: Vladimir P. MATSKO and Tetsuji IMANAKA
Reference: Research Reactor Institute, Kyoto University, July 2002
Keywords: Belarus, food, population, radionuclides
Abstract: Recent data on radionuclide contents of Chernobyl origin in food products and drinking water for the Belarusian population are reviewed. Strontium-90 and Cesium-137 are main radionuclides contributing to internal irradiation to the population. Contamination levels in food products from the social sector of agriculture (collective farms, agricultural co-operatives) are found to be generally below the current legal admissible level of RAL-99 that are defined to make internal dose of the population less than 1 mSv/yr. On the other hand, exceedings of RAL-99 are often found in food products from the private sector, especially in settlements of Gomel region where the contamination is the most serious in Belarus. Special attention should be paid to the non-farm products in the contaminated areas: mushrooms, berries, fish and meat of wild animals. For example, about 37,000 Bq/kg of 137Cs in fresh mushroom was registered in a settlement of Gomel region, which corresponds to 100 times of RAL-99 values. Concerning drinking water, the situation is quite good and no execeedings have been registered for the last 10 years.

Title: Radioactive Contamination of Food in Stepanivka Village, Zhytomyr Region, Ukraine: in 1992 and in 2001
Author: Volodymyr TYKHYY
Reference: Research Reactor Institute, Kyoto University, July 2002
Keywords: contamination, food, Zhytomir region, Ukraine
Abstract: Two series of measurements of radioactive contamination in food samples were performed in 1992 and in 2001 in a village contaminated by the Chernobyl accident. The village, Stepanivka is located 120 km to the west of Chernobyl NPP and has a typical level of Cs-137 surface contamination around that area (3 – 5 Ci/km2). The study was performed by the Independent Environmental Laboratory in Kyiv, jointly founded by the Ukrainian NGO “Green World”, Greenpeace International and the International Renaissance Foundation. It is shown that the Cs-137 contamination in milk in 2001 became 9 times lower than in 1992, while the Cs-137 contamination in wild mushrooms and berries remained at the same level. Annual intake of Cs-137 by the people in Stepanivka through food products and water was about 3 times lower in 2001 than in 1992. On the contrary to the trend of Cs-137, activity of Sr-90 in milk and dried berries was significantly higher in 2001 than in 1992.

Title: Concentration of Radioactive Cesium in Imported Foods and Contribution by Chernobyl Reactor Accident
Author: Kazuyoshi FUKUDA
Reference: RADIOISOTOPES, Vol. 49 (2000) No. 9 P 433-438
DOI: http://dx.doi.org/10.3769/radioisotopes.49.433
Keywords: radioactive cesium, potassium-40, imported food, Chernobyl reactor accident
Abstract: Radionuclides in imported foods consumed in Hokkaido were examined by germanium (Ge) gamma-ray spectrometer system.
The values of radioactive cesium (137Cs+134Cs) concentration of 480 samples collected during 1989-1999 were lower than the temporary limit (370Bq/kg) . These values of 441 samples (92%) were lower than 1 Bq/kg. The maximum values of 137Cs and 134Cs were 62.4Bq/kg, 3.8Bq/kg in black tea imported from China.
From the relation between concentration of 137Cs and cesium unit, the contribution from Chernobyl reactor accident was estimated qualitatively on 24 samples with higher values than 0.40Bq/g-K. Based on the concentration of 134Cs and 137Cs detected in 16 samples, the contribution of 137Cs from this accident were calculated.

Title: Current development of the human and environmental contamination in the Bryansk-Gomel Spot after the Chernobyl accident.
Author: Hille, R / Hill, P / Heinemann, K / Ramzaev, V / Barkovski, A / Konoplia, V / Neth, R
Reference: Radiation and environmental biophysics, 39 (2), p.99-109, Jun 2000
Keywords: contamination, Bryansk-Gomel, soil, food
Abstract: Up to 1991, it was assumed that after the Chernobyl accident in 1986 the time development of radioactive contamination with regard to environment, foodstuff, and man would decrease due to migration processes in the soil, radioactive decay, and protective measures. This assumption was confirmed by all measurements in the first few years after the accident. Since 1991, however, a change in this development has been observed, as many measurements show stagnation or in some cases even an increase of foodstuff and human contamination. If normalised to an average local ground contamination, only a few groups of foodstuffs (e.g., potatoes) show a slight decrease in radioactivity. In this paper, the time development of radioactive contamination in the Bryansk-Gomel Spot on the basis of measurements since 1991 is presented. The consequences for long-term dose assessment are discussed.

Title: Radioecological investigation of food of animal origin in Belgrade environment.

Keywords: food, animals, Belgrade, 137Cs
Abstract: The activity concentrations of 40K, 238U, 232Th and 137Cs were measured using gamma spectrometric method in different food chain samples from Serb Belgrade environment during the periods May-June 2007 and May-June 2008 year. Relatively high activities of 40K and 137Cs were detected in the soil. These results indicate that 137Cs is present in Belgrade environment even 20 years after nuclear accident in Chernobyl. However, in the samples of feedstuffs, animal products and bio indicators (meat of wild animals and fish), activity concentrations of primordial radionuclides and 137Cs were low and below the detection limits. Results of these trials have shown that investigated animal products from the natural environment around Belgrade, are radioactivity safe.
