铀矿井中氡及氡子体的测量

摘要/Abstract

摘要： 本文在特别强调了氡子体测量在氡(²²²Rn)的辐射剂量危害评价中的重要性以后,简要介绍了α能谱法及总α计数法相结合实现同时测量氡气浓度和氡子体浓度的有关方法,用这些方法,对某铀矿的氡及其氡子体的活度浓度、平衡当量浓度等进行了测量。根据该铀矿的氡及其氡子体的测量结果,用有关氡的剂量评价方法,对其进行了剂量评价和估算。测量的数据虽然有限,但从这些测量与剂量评价结果已能看出,铀矿井中的氡、特别是氡子体测量确实值得人们的高度重视。

Abstract: The paper stresses the importance of measuring radon decay daughters in radiation dose evaluations. The measurement methods including alpha spectrometry and gross alpha counting, are introduced and are used to measure the radon and its decay productions in a uranium mine then. The dose estimations and evaluations are performed based on the measurement data of radon and its daughters. It can be seen, though measurement data is limited, that the radiation doses from the radon decay productions should be paid due attention for the radon (particularly, its decay daughters) monitoring in uranium mines.

Key words: radon decay daughters, alpha potential energy, alpha spectrometry, uranium mine, dose estimation
