从氡及其子体的测量入手,介绍了常见的氡气测量方法,并对固体核径迹探测器的探测原理及探测过程进行了分析。设计和研制了静电收集-固体核径迹探测装置,并进行了相关的实验研究。这一方法可以有效地缩短探测时间。一般情况下用固体核径迹探测器测定空气中氡浓度需要将径迹片在环境中放置3个月左右,但通过高压静电场则只要不到一周的时间即可以达到饱和收集。提出的方法能够在较短的时间内提供较准确的放射性氡浓度,研制的实验装置具有一定的应用价值。
Starting with the measurement of radon and its daughters, the common radon measurement methods are introduced, and the detection principle and detection process of solid nuclear track detectors are analyzed. Design and development of electrostatic collection - solid nuclear track detection device, and the relevant experimental study. This method can effectively shorten the detection time. In general, using solid nuclear track detectors to measure radon concentration in the air requires the track patch to be placed in the environment for about 3 months, but through a high-voltage electrostatic field, saturation can be achieved in less than a week. The proposed method can provide more accurate radioactive radon concentration in a short period of time, and the experimental device developed has certain application value.
