【摘要】 本文介绍被动式活性炭氡采样器扩散控制管设计参数的选择方法。通过对活性炭吸附氡量与暴露时间的关系式的线性化处理,选择了适当的扩散控制管的参数,可以大大减小温度对测量结果的影响,同时可保持探测器有较高的灵敏度。更多还原

【Abstract】 This paper describes a methed concerning selection of design parametes of diffusion barrierin a passive ²²²Rn sampler based on activated charcoal adsorption.The proper parameter value of diffu-sion barrier is obtained by means of linearization of ²²²Rn 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.更多还原
