摘要
许多设施建立在被岩石土壤包围的地下空间,该工程中氡及其子体浓度远远超出规定的限值,氡致内照射剂量较高,严重威胁工作人员的身体健康与生命安全。该文对比介绍屏蔽降氡、通风降氡和净化降氡3种方法降低大区域地下设施空间氡致内照射剂量的优缺点,为控制大区域地下空间中氡及其子体对工作人员造成的氡致内照射剂量较高的问题提供思路指导。
Many facilities are built in underground spaces surrounded by rock and soil.The concentration of radon and its progeny in this project far exceeds the specified limits.The internal exposure dose caused by radon is high,which seriously threatens the health and life safety of workers.This paper compares the advantages and disadvantages of three methods:shielding radon reduction,ventilation radon reduction and purification radon reduction to reduce radon-induced internal exposure doses in large-area underground facility spaces,and provides guidance for controlling the problem of high radon-induced internal exposure doses caused by radon and its progeny to workers in large-area underground spaces.
