摘要
目的:为了解吉林省饮用水中放射性水平。方法:依据《生活饮用水卫生规范》和《饮用天然矿泉水标准》,采用BH1217型弱α,β测量仪和FD一125室内氡钍测定仪,对饮用水总α、总β和5个行政区域矿泉水中226Ra放射性水平分析测定。结果:自来水,深井水的总α放射性含量分别为13×10-3Bq/L,16.7×10-3Bq/L。总β放射性含量分别为82×10-3Bq/L,71×10-3Bq/L,57×10-3Bq/L。五个行政区域的226Ra平均值为8.6×10-3Bq/L。结论:吉林省生活饮用水中总α、总β和226Ra放射性活度在国家卫生标准限值范围内。
Objective： Determination of Radioactivity Level of drinking water of jilin Province.Methods： According to the Standards for Drinking Water Quality and Standards for natural mineral water Quality,we detected the Total alpha,Totalbeta and 226Ra activities in the samples of drinking water and natural mineral water which were selected from five regions in Jilin Province.During the process,the BH1217 type Weak α,β＇ Survey Meter and FD-125 type Indoor Radon,Thorium Analyzer were used.Results： The contents of Total α of tap water and deep well water are： 13×10-3Bq/L,16.7×10-3Bq/L;the contents of Total β of tap water and deep well water are： 82×10-3Bq/L,71×10-3Bq/L,57×10-3Bq/L;and the mean value of the 226Ra,which came from the data of five regions,is 8.6×10-3Bq/L.Conclusion： The radioactivity levels of Total α,Total β and 226Ra of drinking water of Jilin Province were within the range of the national standards.
