该文从氡(Rn)的微观析出机制、结合态子体与未结合态子体的形成机制与特征、氡危害的实质与研究热点进展进行综述。提示应进一步加强氡子体在室内的分布特征、影响因素及其控制技术研究;同时氡同位素在污染水体的示踪技术领域亦具有较广的应用空间。
The paper attempts to illustrate some aspects briefly of microcosmic rationale of radon (Rn) exhalation, forming mechanism and characteristics of attached and unattached decay products, the scientific nature of the Rn harming mechanism and its hot topic of research and progress. The research perspective involves the strengthening study on distribution, influencing factors and its mitigation measures of indoor Rn decay products. In the field of tracing technology of waste water discharge, the Rn isotopes have a promising potential in related application.
