Abstract: To evaluate current environmental contamination and contributions from internal and external exposure due to the accident at the Chernobyl Nuclear Power Plant (CNPP) and nuclear tests at the Semipalatinsk Nuclear Testing Site (SNTS), concentrations of artificial radionuclides in edible mushrooms, soils and stones from each area were analyzed by gamma spectrometry. Annual effective doses were calculated for each area from the cesium contamination. Calculated internal effective doses of 137Cs due to ingestion of mushrooms were 1.8 × 10–1 mSv/year (y) in Gomel city (around CNPP), 1.7 × 10–1 mSv/y in Korosten city (around CNPP), 2.8 × 10–4 mSv/y in Semipalatinsk city, and 1.3 × 10–4 mSv/y in Nagasaki.
