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.

Abstract: The authors describe validity of the principles of the existing iodine prophylaxis in this country, levels of intervention and adopted doses of protective preparations from the point of view of modern knowledge. They state that possibility of cancer diseases progress may be reduced or even totally prevented using iodine pro-phylaxis, and to the larger extent using it in combination with other protective measures; the main principle of iodine prophylaxis must be an achievement of a ma-ximum effect using minimum doses of potassium iodide for each age cohort.

Keywords: Radiocaesium; Fish; Chernobyl; Modelling
Abstract: The radiocaesium concentration factors (CF) of different fish species in 10 lakes in Russia, Belarus and Ukraine were measured between 6 and 11 yr after the Chernobyl accident. Clear inverse relations were observed between fish CF and lakewater K+ concentration.

doi: 10.1016/S0265-931X(02)00134-0
Keywords: Modelling; Radiocaesium; Fish; Chernobyl
Abstract: After the sudden fallout from the Chernobyl nuclear accident in 1986, activities and bioaccumulation factors of radiocaesium (137Cs, 134Cs) fluctuated strongly over several years before reaching quasi-equilibrium, with patterns significantly differing among organisms.
