目的了解广州军区部队生活饮用水的总α、总β放射性水平。方法对广州军区部分部队生活饮用水进行采样,应用MPC9604型四路低本底α、β计数器测量仪,用241Am和KCl作为α、β放射性测量的标准源,采用中等厚度相对测量法测定样品中的α、β放射性活度浓度。结果各种样品总α放射性水平为(2.04±1.00)×10-2~(5.06±4.15)×10-2Bq/L,总β放射性水平(3.79±3.41)×10-2~(6.54±1.78)×10-2Bq/L,β/α值为0.95~3.21。结论本次监测样品均符合国家饮用水标准,未见人工放射性核素污染。
Objective To understand the total α and total β radioactivity of drinking water in the army of Guangzhou Military Region. Methods Samples of drinking water of some troops in the Guangzhou Military Region were sampled. Using the MPC9604 four-channel low background α, β counter measuring instrument, 241Am and KCl were used as the standard sources of α, β radioactivity measurement. Of α, β radioactivity concentration. Results The total radioactivity levels of various samples were (2.04 ± 1.00) × 10-2 ~ (5.06 ± 4.15) × 10-2Bq / L and the total β radioactivity levels were 3.79 ± 3.41 × 10-2 ~ (6.54 ± 1.78) × 10 -2 Bq / L, and the β / α value is 0.95 to 3.21. Conclusion The monitoring samples are in line with the national drinking water standards, no artificial radionuclide contamination.
