| 中文摘要: |
| 采用一种用活性炭吸附法测量介质表面氡析出率的方法，并就反扩散对氡析出率测定的影响进行了探讨，实验比较了孔隙度不同的介质反扩散对氡析出率测量值的影响，从而可为测量不同介质氡析出率时，适宜采样时间的选取提供参考依据。 |
| 英文摘要: |
| The method of determining the radon exhalation rate from the materials surface by the activated charcoal absorption is introduced in this paper.The effect of the back diffusion for determining radon exhalation rate is also discussed.The back diffusion effects of different porosity of the materials are compared,and our experiment result is provided.The result is helpful for the decision of the exact sampling time to determine the radon exhalation rate by the instrumentality of activated charcoal absorption. |
