摘要
地下工程深入地下,密闭性好,通风能力差,氡辐射浓度远高于国家规定的标准.地下工程中,岩石、土壤、地下水以及建筑材料均会释放氡,但影响地下工程氡辐射浓度释放的因素较多.以某地下工程为例,通过对其在不同季节和通风条件下进行氡辐射浓度监测,研究气温和通风对地下工程氡辐射浓度释放的影响,为地下工程后续氡辐射污染治理方案设计提供科学的数据支撑,消除影响地下工程工作人员身体健康的放射性危害因素,助力"健康中国"建设.
Abstract
Underground engineering is deep underground with good confinement and poor ventilation,and the radon radiation concentration is much higher than the national standard.In underground engineering,rocks,soil,groundwater and construction materials will release radon,but there are more factors affecting the release of radon radiation concentration in underground engineering.Taking an underground project as an example,by monitoring its radon radiation concentration under different seasons and ventilation conditions,we study the influence of air temperature and ventilation on the release of radon radiation concentration in underground projects,provide scientific data support for the design of subsequent radon radiation pollution control programs for underground projects,eliminate the radioactive hazardous factors affecting the health of underground project workers,and contribute to the construction of a healthy China.
