摘要
氡是一种天然产生的放射性气体,大气环境中氡的主要来源是天然铀元素衰变成镭,镭衰变成氡,大气环境中氡浓度在24 h内呈一定趋势有规律的变化,通过选取典型监测点位,验证分析了氡气浓度的一日变化趋势。
Radon is a naturally produced radioactive gas.The main source of Radon in the atmosphere is from natural uranium element decaying into radium and radium decays into radon.The daily variation trend of radon concentration was verified and analyzed by selecting typical monitoring sites.
