关于水中总α总β放射性测量监测方法改进的探讨

Discussion on Improvement of Monitoring Method for Grossαand Grossβradioactivity in Water

目前国内关于水中总α、总β放射性测量相关标准还不够细化,操作规程在一些细节方面还存在部分问题,为减小实验误差,提高实验准确度,对监测方法进行了改进。对前期水中总α、总β放射性监测的实验过程进行经验总结,对实验条件进行优化改进,通过回收率和准确度对实验结果进行验证。对水中总α、总β放射性监测实验过程中的水样放置时间、蒸发过程、硫酸盐化、研磨工具、铺样试剂、本底测量、测量条件及质量控制等方面进行了改进,通过了回收率和准确度的验证,符合实验要求。本提高了工作效率,减小了实验误差,提高了实验的准确度和可靠性。

At present,the relevant standards for the measurement of gross alpha and gross beta radioactivity in water in China are not detailed enough,and there are still some problems in some details of the operation procedure.In order to reduce the experimental error and improve the experimental accuracy,the monitoring method is improved in this paper.in this paper,the experimental process of grossαand grossβradioactivity monitoring in water was summarized,the experimental conditions were optimized and improved,and the experimental results were verified by recovery rate and accuracy.TThe water sample placement time,evaporation process,sulfate,grinding tool,sample laying reagent,background measurement,measurement conditions and quality control were improved in the experimental process of grossαand grossβradioactivity monitoring in water,which passed the verification of recovery and accuracy and met the experimental requirements.This method improves the working efficiency,reduces the experiment error,and improves the accuracy and reliability of the experiment.
