地下建筑和矿山,包括非铀矿山,普遍存在着氡及其子体的污染,本文则系统地叙述了这种污染的来源、目前污染状况,对人的危害以及防护措施等。作者认为,要有效防治氡及其子体的污染,必须采取超压通风,合理确定进排风量和滤、吸、堵等综合技术措施。文中提出的通风风量计算公式简单方便,可供设计计算使用。
Underground buildings and mines, including non-uranium mines, are generally polluted by radon and its daughters. This article systematically describes the sources of the pollution, current pollution, human hazards, and protective measures. The author believes that in order to effectively prevent the contamination of fleas and their daughters, it is necessary to adopt overpressure ventilation, reasonably determine the intake and exhaust air volume and comprehensive technical measures such as filtration, suction, and plugging. The ventilation volume calculation formula proposed in the paper is simple and convenient, and can be used for design calculation.
