被动累积测氡方法广泛用于环境监测氡浓度水平长期调查,其中固体核径迹(SSNTD)测氡方法是最主要的被动累积测氡方法。本文主要从原理、采样、测量、结果表示等方面介绍国际ISO1165-4号标准中关于固体核径迹(SSNTD)被动累积测氡方法。
Passive accumulation of radon measurement methods are widely used in the long-term investigation of radon concentration levels in environmental monitoring. The SSNTD radon measurement is the most important passive accumulation radon measurement method. In this paper, we mainly introduce passive accumulation of radon measuring method (SSNTD) in the international standard ISO1165-4 from the aspects of principle, sampling, measurement and result representation.
