摘要
气溶胶中钋-210分析项目无国家标准方法可依据,为更好完成辐射环境监测质量任务中气溶胶中钋-210,了解气溶胶中钋-210的放射性水平,开展气溶胶中钋-210方法确认。依据《水中钋-210的分析方法》(HJ813-2016),研究结果显示,平行样测量结果的平均值为0.318mBq/m3,相对标准偏差为15.4%,实验室间比对结果的相对标准偏差为11.4%。通过精密度、准确度、检出限等实验,确认气溶胶中钋-210分析方法的可行性,具备气溶胶中钋-210监测分析的能力。
The Polonium-210 Analysis Project has no national standard methodology to support it.In order to better Environmental monitoring polonium-210 in the aerosols to better understand the level of radioactivity in the aerosols,to develop a method to confirm the presence of polonium-210 in aerosols.According to the Analysis of Polonium 210 in Water(HJ813-2016).Results showed:the average value of parallel sample was 0.318 mBq/m3,Relative standard deviation was 15.4%,Interlaboratory comparison of results was 11.4%.Through the experiments of precision,accuracy and detection limit,the feasibility of polonium-210 analysis method in aerosol is confirmed,and it has the capability of monitoring polonium-210 in aerosol.
