The radioactive noble gas radon is identified as the highest risk factor for lung cancer after smoking. The exhalation of radon from building materials can contribute to the radon indoor activity concentration. Therefore, the emanation of radon might be a crucial factor. It is defined as the release of radon from the solid soil matter into the pore space of the material. This article describes a new on-site measurement method for the emanation of radon from building materials at industrial sites. Therefore, a closed vessel with sample material and a passive radon detector inside is used to measure the integrated build-up-curve of the activity concentration. Additionally, a brief overview on existing radon emanation measurement methods is given.
放射性惰性气体氡被认为是仅次于吸烟的肺癌最高风险因素。建筑材料中氡的析出会导致室内氡活度浓度升高。因此，氡的析出可能是一个关键因素。它被定义为氡从固体土壤物质释放到材料孔隙空间的过程。本文介绍了一种在工业场所测量建筑材料中氡析出的新现场测量方法。因此，使用一个装有样品材料和内部有被动式氡探测器的密闭容器来测量活度浓度的积分累积曲线。此外，还对现有的氡析出测量方法进行了简要概述。
