| 摘 要： | 参考《土壤中锶-90的分析方法》(EJ/T1035-2011),对2009—2016年间北京市某监测点气溶胶中~(90)Sr放射性水平进行监测。历年监测数据以及异常数据的分析表明:北京市某监测点气溶胶中~(90)Sr放射性活度浓度范围约为0.051 2~0.444mBq/m~3;持续性大雾可导致大气中的固体颗粒物含量发生变化从而可能导致气溶胶中~(90)Sr的放射性水平升高。

| Abstract: | With reference to analytical method for 90Sr in soil(EJ/T 1035-2011), the radioactive level of 90Sr in aerosol was monitored in Beijing from 2009 to 2016. The results indicate that, the range of radioactive concentration of 90Sr in aerosol at the monitoring point in Beijing is 0.051 2-0.444 mBq/m3. The analysis of abnormal data shows that, the radioactive concentration of 90Sr in aerosol will possibly increase as the changes of the content of solid particles in the atmosphere caused by durative fog. |
