摘要
阐述了GB 50325-2001《民用建筑工程室内环境污染控制规范》中存在的问题,指出该规范仅对建筑材料放射性的测量不确定度D(当K=1时,D≤20%)提出了要求,未对测量时间、仪器测量下限和放射性物质特征峰漂移提出要求。实验证明,这些存在的问题对建筑材料放射性测量数据的准确性有影响。
This paper describes existing problems in the standard （ GB 50325 - 2001 ）. This document sets limits only for the uncertainty of radioactivity measurements of building materials ≤20% （K = 1 ）. There are no requirements on important parameters such as measurement time, limit of measurement and characteristic peak drift of radioactivity. Our experimental results indicate that the lack of requirements in the areas above will have a negative impact on the precision and accuracy of radioactivity measurements on building materials.
