| 摘 要： | 氡及其子体是天然本底辐射剂量的主要贡献者，是当前的一个研究热点。设计了一种简易的表面氡析出率测量装置，可以用来测量某些样品表面的氡析出率。为了了解所设计装置的性能，对不同氡析出率大小的样品进行了测量，同时对这种防氡涂料的防氡效果进行了测评。测量结果表明，该测量装置可较为准确地给出所测样品的表面氡析出率，且性能稳定、操作简便，可改进余地较大，缺点是测量耗时较长。

| Abstract: | Radon and its daughters is a major contributor to natural background radiation dose, and it is a hot research topic now. In this paper, a simple radon measuring device of surface exhalation rate is designed, and it can be used to measure the radon exhalation rate of some sample surface. To understand the performance of the device, the radon exhalation rate of different samples are measured, and the measurement also verified the anti-radon effects of certain anti-radon coating. The measurement result shows that the radon surface exhalation rate of the sample can be given more accurate by the measuring device, but the measurement takes a long time. The device is of stable performance, easy to operate, but has some room to improve. |
