| Abstract: | 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. |
