The concentrations of Cs and potassium in the surface layers of arable soils were analyzed in the selected region of Eastern Poland approximately 20 years after the Chernobyl power plant accident. Additionally, the occurrence of the elements in soil in the forms available for plants was determined. In relation to the total concentrations of Cs and K in the soil, cesium is found in larger quanti...

Deep water samples collected in 1963 and 1964 in the adjacent seas of Japan were analyzed radiochemically. Sr-90 and Cs-137 were detected in the deep layers down to 6,000 meters deep and showed approximately uniform vertical distributions below 1,000 meters. Mean concentrations of Sr-90 in deep waters were 0.028 ƒÊƒÊc/l in the Pacific and 0.035ƒÊƒÊc /l in the northern Japan Sea, and those of Cs...
