福岛核事故期间杭州地区雨水中^(131)I监测

Concentration Level Monitoring of ^(131)I in rainwater during Event of Nuclear leakage in Japan

福岛核事故应急监测期间,在杭州采集到的雨水样品中检测出了微量的131I,用放化法和γ谱法测得的结果分别为0.18 Bq/L和0.24 Bq/L。两种方法的测量结果基本一致。

In this article, the emergency monitoring of 13a I in rainwater during the event of nuclear leakage in Japan was introduced. The results showed that there was trace 131I in rainwater of Hangzhou. The concentration of 131I in rainwater measured using radiochemical method and 7 spectrometry were 0.18 Bq/L and 0.24 Bq/L, respectively, and the results were in good agreement between the both.
