在日本国家放射科学研究所对集成探测器进行了国际比对，其中24.4m(3)的内部体积步入式氡室具有控制氡浓度、温度和湿度的系统。在第一次比对(05.2007)期间，来自4个国家的4组参与者参加了第二次比对(10.2007)。在第二次比对(10.2007)中，来自11个国家的17名参与者参与了比对。大多数探测器与氡室提供的氡水平相比，彼此之间的一致性很好。70%的探测器似乎在20%的不确定度范围内是统一的。(C)2009爱思唯尔有限公司。保留所有权利。
An international intercomparison of integrating detectors was conducted at NIRS (National Institute of Radiological Science, Japan) with a 24.4 m(3) inner volume walk-in radon chamber that has systems to control radon concentration, temperature and humidity.During the first intercomparison (05.2007) four groups participated from four countries and for the second intercomparison (10.2007) 17 participants were involved from 11 countries.Most of detectors are in good agreement with each other when compared to the radon level provided by the radon chamber. It appeared that the 70% of detectors are unified within the 20% margin of uncertainty. (C) 2009 Elsevier Ltd. All rights reserved.
