摘要：

Radon exhalation rate from soil is one of the most important factors for evaluation of the environmental radon level. For rough estimation of the nationwide radon exhalation rate from soil in China, a simple model was derived under the review and analysis of several previous works on radon exhalation theories. To show the feasibility of the model, some nationwide databases were summarized and discussed, and a trial estimation was made and compared with the measured data for Beijing. The results show that it is possible to map the radon exhalation rate from soil in China based on the present databases.
