摘要：
The exhalation rate of radon from different materials were measured using CR-39 solid state nuclear track detectors (SSNTDs). The radon exhalation rate varies from 52 to 117 mBq.m(-2) h(-1) in soil samples, from 50 to 73 mBq.m(-2) h(-1) in coal samples and from 78 to 96 mBq.m(-2) h(-1) in fly ash samples, respectively. In two soil samples, the radon exhalation rate is higher than the fly ash samples. This may be due to the low emanation power of fly ash, as the radionuclide contents of fly ash are found to be higher than the soil by various investigations.
