摘要
目的:了解2016-2017年山东省部分地表水中锶-90放射性水平。方法:根据GB6766-86《水中锶-90放射化学分析方法二-(2-乙基己基)磷酸萃取色层法》。结果:2016、2017年山东省部分地表水中锶-90的放射性活动浓度范围分别为0.57～5.82mBq/L和0.51～5.50mBq/L。结论:2016-2017年山东省地表水中锶-90放射性活度浓度含量变化相对平稳,均处于正常的自然环境本底范围内。
Objective:To monitor strontium-90 radioactivity level of ground water in Shandong province from 2016 to 2017. Method: According to "Radiochemical analysis of strontium-90 in water Extraction chromatography by di-(2-ethylhexyl) phosphoric acid"(GB6766-86). Results: The activity concentration of strontium-90 of ground water in Shandong province from 2016 to 2017 were in the range of 0.57～5.82 mBq/L and 0.51～5.50 mBq/L. Conclusion: From 2016 to 2017, the concentration of strontium-90 radioactive activity of ground water in Shandong province changed smoothly, and both of them were within the background range of natural environment.
