Analysis of Foods for Cesium-137

Nucleonics

“…Gamma radioactivities found in boreholes drilled in shales, limestones, and sandstones, activated by a neutron source were also measured (246), as were Eu152-Eu164 mixtures (1133). Mixtures of Fe54, Mn54, Crbl, and W181 (1761); Cs134 in alkali salts (1564); I131 in feces (385) and hormones (1355); Th, U, and Kin basalts (634); Th, U, and K in ocean bottom cores (783); Th and U in rocks (169, [670][671][672]; radionuclides in water (286, 288, 773, 1331, 14 , 1476), and geochemicals (334); K40 in soils (592); K40, Rb11, U238, U235, and Th232 (366, 608,849); Cs137 in Co60 mixtures (197); U, Ra, Th, and K in granite rocks (335,366, I486, 1578) and soils and water (414)(415)(416); Cs137 in foods (1730) and dust (724), and Pa231 in uraninites (1553) and Sr" in bones (1317) were also determined by gamma spectrometry. Owen (1244) reports on the use of -spectrometry to measure the burnup of irradiated fuel elements.…”
