Abstract

The World Health Organization (WHO) recommends that countries adopt the reference level of 100 Bq m-3 for indoor radon gas. Adopting the reference level requires a preliminary assessment of the indoor radon concentration. In the preliminary investigation, a cut-off value is useful, which is a value for selecting samples that can be reliably determined to be below the reference level (in this paper, the WHO reference level) using a straightforward method. If the true value was the WHO reference level, then the cut-off value of the PicoRad collector for selecting samples was determined as 80 Bq m-3 through the analysis of the 95% prediction interval.

摘要

世界卫生组织（WHO）建议各国采用室内氡气的参考水平 100 Bq m-3。采用参考水平需要对室内氡浓度进行初步评估。在初步调查中，截止值是有用的，它是使用简单方法可以可靠地确定低于参考水平（在本文中为世界卫生组织参考水平）的样本的选择值。如果真实值是世界卫生组织的参考水平，那么通过分析 95%预测区间，皮考拉德收集器用于选择样本的截止值确定为 80 Bq m-3。
