Strontium-90 and cesium-137 in seaweeds (from Feb. 1985 to Jun. 1985)

Description

Sr-90 and Cs-137 in seaweeds (Undaria pinnatifida) were determined using radiochemical analysis. Two to three kg of edible seaweeds was collected during the fishing season from six sampling locations. The seaweeds were rinsed with water to remove sand and other adhering matters on the surface. These were removed of excess water, weighed, dried and ashed. The maximum value of Sr-90 was 2.1 +- 0.32 pCi/kg in seaweeds collected from Yamagata in June 1985; and that of Cs-137 was 1.6 +- 0.24 pCi/kg in seaweeds from Nagasaki in February 1985.
