摘要
Abstract
The detection method of 210 Po in the surface water around the decommissioned uranium mine was studied,and the activity level of 210Po in the surface water around the uranium mine was investi-gated.Using iron(Ⅲ)hydroxide as the carrier,210Po in the water sample was adsorbed and allowed to self-deposit on a copper plate in a hydrochloric acid-sodium chloride system,and then measured on an alpha spectrograph.The detection limit of the method is 0.001 Bq/L,the precision is better than 10％,and the recovery is between 93.4％and 106.6％.The results show that the activity concentra-tion of 210 Po in the surface water around the decommissioned uranium mine is between 0.001 and 0.223 Bq/L,indicating a certain level of pollution.There is a risk of transferring to humans through drinking water and food chain,resulting in an increase in internal exposure dose to residents.It is necessary to strengthen monitoring of surface water around the uranium mine and evaluation of public exposure.关键词
