【摘要】 根据2017—2020年逾2 000台(次)的测氡仪检定数据,对年增长率、合格率以及参数分布等进行了分析。采用“后续检定合格率”评价仪器的长期稳定性及参数变化情况,采用相对标准偏差分析常见类型测氡仪的体积活度响应,结果表明:连续测氡仪的后续检定合格率比瞬时测氡仪高,RAD7型测氡仪的一致性最好,对数据分析结果进行了原因剖析并提出了建议。分析数据具有代表性,可为测氡仪生产厂家,用户及研究人员提供基础数据及分析结果,以便更好了解行业现状。更多还原

【Abstract】 According to the verification data of more than two thousand radon measuring instruments from2017 to 2020,the annual growth rate,the qualified rate and the distribution of parameters were analyzed.The long-term stability and parameter changes of the instrument are evaluated by the " subsequent verification qualification rate",and the volume activity response of common types of radon measuring instruments is analyzed by the relative standard deviation.The results show that the subsequent verification qualification rate of continuous radon measuring instruments is higher than that of instantaneous radon measuring instruments,and the consistency of RAD7 radon monitor is the best.This paper analyzes the reasons for the data analysis results and puts forward some suggestions.The analysis data were representative,which can provide basic data and analysis results for radon monitor manufacturer,users and researchers,so as to better understand the current situation of the industry.更多还原
