The four passive samplers (quatrefoil) already described in a parallel paper, make it possible to obtain thin radiation sources, useful for alpha and beta counting by any passive and real-time detector. In the present paper, the applications of this quatrefoil for measuring radon gas by etch-track detectors will be described. In the case of radon measurements, different solids have been identified, with radon-sorption partition coefficients related to air from 1 to 2000. Uniquely compact radon badges can be obtained by using a layer of these solids facing an alpha track-etch detector. These radon badges make it possible to overcome most of the shortcomings of existing passive monitors. Moreover, these badges show promise for studying the radon solubility of polymer films.
在一篇平行论文中已经描述过的四个被动采样器（四叶形），能够获得薄辐射源，这对任何被动式实时探测器进行α和β计数都很有用。在本文中，将描述这种四叶形采样器在通过蚀刻径迹探测器测量氡气方面的应用。在氡测量的情况下，已经确定了不同的固体，其与空气的氡吸附分配系数在1到2000之间。通过使用一层这些固体面对α径迹蚀刻探测器，可以获得独特紧凑的氡徽章。这些氡徽章能够克服现有被动监测器的大多数缺点。此外，这些徽章在研究聚合物薄膜的氡溶解度方面显示出前景。
