摘要
对北京房山区某煤矿、浙江安仁某煤矿氡活度浓度和γ辐射剂量率进行测量,结果表明:在自然通风条件下,煤矿井下氡活度浓度较高,且随季节有着显著的变化;氡活度浓度与通风和煤的氡析出行为关系密切。
Investigation and measurement of radon concentration and gamma-radiation dose rate were carried out in a coal mine in Fangshan Area of Beijing and a coal mine in Anren town of Zhejiang. The results show that underground radon concentrations in two coal mines were high under the condition of nature ventilation, have significant changes with seasons, and radon concentration was closely related to ventilation and radon exhalation behaviors.
