Description
In order to improve the detection limit of artificial radionuclides, following measurement procedures were applied to a seaweed (Sargasso) sample collected in the vicinity of Shika Nuclear Power Station; method-1 (use of Ge-LEPS in Ogoya underground laboratory), method-2 (40K removal + Ge-LEPS in underground lab.) and method-3 (40K removal + well type Ge in underground lab.). By these measurements, the activities of low level artificial radionuclides of the Sargasso sample were below the detection limit, suggesting that the background level of 108mAg, 110mAg and 60Co was < ∼ 8 mBq/Kg-fresh.
