Hisamatsu, Y. Takizawa, T. Abe] Americium and plutonium concentrations in food samples and human tissue samples were determined using alpha-ray spectrometry. Food samples, representative of the average dietar intake over a period of 30d in Japan, were pruchased in Akita during 1985 and 1986. The food was divided into six groups: cereals, vegetable, fruits/beans, seaweeds, fish/shellfish, and meats/eggs/milk. Most of the. total ingestion of both Pu and Am was contributed by seaseed and fish/shellfish. The concentration of Am in the other food groups was low. A compoarison of the measured241Am/239+240Pu ratio in human liver with the predicted value of the ICRP-30 or ICRP-48 model showed that the half-life of Am in the liver is approximately 2-10y. The human tissue samples were obtained from subjects who died in Akita and Niigata Prefectures in northern Japan during 1981-1984. The median concentration of241Am was 1.4 mBq/kg-wet in the stemum (n=11), 3.4 mBq/kg-wet in the liver (n=19), and 0.5 mBq/kg-wet in the lung (n=15). The ratio of241Am/239+240Pu was 0.34 in the sternum, 0.12 in the liver, and 0.14 in the lung. Akadémiai Kiadó, 1990 Hisamatsu S.
