摘要

氡及其子体是对人体造成天然辐射的主要来源,尤其是未结合态氡子体对于人体危害更大。本文根据风扇模型扩散理论对结合态与未结合态氡子体采样器进行改进研究,研制出新型联丝网组可以对结合态和未结合态氡子体同时进行实验测量,为后续研究未结合态氡子体变化规律打下了基础。
        Radon and the progeny is the main source of natural radiation to human body. Particularly,the unattached radon progeny has great danger to human. This paper,according to fan model diffusion theory,studies on the improvement of the sampling device of attached and unattached radon progeny. Combined with theoretical research and experiment measurement,the new graded screen arrays have been developed to measure attached and unattached radon progeny. It can form a base for further research.
