| Abstract: | This paper describes a methed concerning selection of design parametes of diffusion barrierin a passive ~(222)Rn sampler based on activated charcoal adsorption.The proper parameter value of diffu-sion barrier is obtained by means of linearization of ~(222)Rn adsorption versus the exposure time.Thus,the influence of temperature on measured results may be greatly decreased,and higher sensitivity of thedetector may be maintained. |
