建材氡析出率测量及影响因素分析
|
摘要
简述闪烁室法测量建材氡析出率的方法;对几种常见建材样品进行氡析出率测量;分析了解了氡析出率的影响因素:温度、湿度、气压等气象因子;建材的射气系数、扩散系数;测量过程中系统引起的测量误差。
This paper briefly introduced the scintillation chamber method for measuring radon exhalation rate. Several common building materials samples were measured for radon exhalation rate,the influencing factors of radon exhalation rate were analyzed which are temperature,humidity,air pressure and other meteorological factors,emanation coefficient and diffusion coefficient of building materials. Measurement errors caused by the system during measurement.
