目的了解沈阳市区各类水体中总α、总β放射性水平。方法使用BH1227型四路低本底α、β测量系统,按照(GB/T 5750-2006)《生活饮用水标准检验方法放射性指标》的要求进行水样的采集、处理和测量。结果沈阳市区各类水体的总α水平在(0.162±0.004)×10-2~(8.943±0.061)×10-2Bq·L-1之间;总β水平在(0.3149±0.0086)×10-1~(1.201±0.0246)×10-1Bq·L-1之间。结论沈阳市区各类水体的总α、总β放射性水平均在国家规定标准范围以内。
Objective To understand the total α and total β radioactivity in various types of water in Shenyang city. Methods The BH1227 type four low background α, β measurement system was used to collect, process and measure water samples according to the requirements of (GB / T 5750-2006) “Radioactive Index for Standard Test Method for Domestic Drinking Water”. Results The total α level of various water bodies in Shenyang was between (0.162 ± 0.004) × 10-2 ~ (8.943 ± 0.061) × 10-2Bq · L-1 and the total β level was (0.3149 ± 0.0086) × 10- 1 ~ (1.201 ± 0.0246) × 10-1Bq · L-1. Conclusion The total α and total β radioactivity of all kinds of water bodies in Shenyang are all within the national standard range.
