摘　　要：金矿等非铀矿山开采过程中存在放射性污染的问题。阐述了氡及其子体对作业人员可能产生的危害,针对氡气扩散运移机制的不同,提出相应的防护措施。通过合理调整地下通风、设置实物屏障、采用化学吸附及安装高效空气过滤器等手段控制氡的扩散和渗流,从而减少矿井中氡的浓度。通过对矿井中的氡及其子体浓度进行监测,加强人员防护及矿井管理,可使作业人员所受的放射性伤害尽可能低。The radioactive contamination problems in gold mining are concentrated in this paper,possible hazard made by radon and radon daughters must be pay great attention.Through the researches for radon gas transfer and permeate mechanism,we proposed appropriate protective measures for different condition.This paper puts forward useful methods of reasonable adjusting the ventilation system in underground mine,setting practicality barrier,using chemical adsorbed mater,and installing high efficiency air filter for controlling the spread and seepage of radon, reducing the concentration of radon and radon daughters in the mine.Routine monitoring in the mine,personnel protection and mine management, also help to reduce workers suffered radiation injury as low as possible.
