… A simple method of evaluating Sr-90 concentration in these water samples by measuring β rays from Y-90 with a GM-detector setup was developed. … β rays from Y-90 in the filter were measured two times at appropriate intervals by inserting a polyethylene plate of 2 mm thickness as a β-ray absorber. … The contribution of γ rays from Cs-134 and Cs-137 to the Y-90 count rates was quantitatively evaluated using a 10-mm-thick acrylic resin plate. …

水中90Sr放射能濃度の90Yβ線測定による迅速簡便測定法

平山英夫,近藤健次郎,海野泰裕,松村宏,岩瀬広,柚木彰,佐々木慎一
日本原子力学会和文論文誌 14(3), 141-150, 2015
… A rapid and simple method to measure the concentration of 90Sr in water by measuring β-rays from 90Y was presented. … Under the situation that 90Sr/90Y, 134Cs and 137Cs are the main radionuclides included in the water sample, only β-rays from 90Y can transmit through 1.5-mm-thick polyethylene. … From this fact, it is possible to measure β-rays from 90Y using a β-ray detector, such as the GM-counter, set beneath the 1.5-mm-thick bottom of the water bottle containing the sample with 90Sr/90Y. …
