Development of a practical detector for collecting Rn by adsorption in charcoal with a time integration of 2 d or more, achieved by use of a diffusion barrier through which Rn enters, is described. The sensitivity is adequate for monitoring Rn levels in houses. It is easily sent and returned by mail, and instructions for use are simple enough for any householder to follow. The cost per measurement is apparently well below that for competitive techniques.
本文描述了一种实用探测器的研制情况，该探测器通过使用氡进入的扩散屏障，以实现2天或更长时间的时间积分，利用木炭吸附来收集氡。其灵敏度足以监测房屋内的氡水平。它易于通过邮件发送和返还，使用说明简单到任何住户都能遵循。每次测量的成本显然远低于竞争技术。
