摘要: 氡析出率的测量对于我国铀矿冶设施退役治理具有重要意义,是评价铀尾矿库防氡覆盖治理效果的关键环节。针对我国铀尾矿库氡析出率调查工作量大、仪器测量周期长的问题,本研究提出基于驻极体的氡析出率技术方法,缩短氡析出率测量时间,以此增加每日布置测量点位的频次,实现对广域铀矿冶场所氡析出率的快速调查。实验室校准和现场应用结果表明,该方法装置可靠、方法可行、结果可信,在氡析出率测量点位数量相同条件下,驻极体法测量耗时是RAD7测量耗时的2/9。

Abstract: The measurement of radon precipitation rate is of great significance to the decommissioning of China’s uranium mining and metallurgical facilities, and is a key link in evaluating the treatment effect of uranium tailing dams against radon precipitation. In view of the large workload of investigation on radon precipitation rate in uranium tailing dams in China and the long measurement period of instruments, this study proposes a technical method based on electret radon precipitation rate, which shortens the measurement time for radon precipitation rate and increases the daily measurement points. The increased frequency of measurement can be used to quickly investigate the radon precipitation rate in wide-area uranium mining and metallurgical sites. The results of laboratory calibration and field application show that the device is reliable, the method is feasible, and the result is credible. Under the same conditions of the number of measurement points for the radon precipitation rate, the electret method is 2/9 of the RAD7 measurement time.

Key words: radon precipitation rate, electret, high efficiency, measurement period
