| 摘 要： | 本文根据介质表面氡析出率的测量原理,针对目前国内外现有的氡析出率测量方法中存在的一些问题,如对氡及其子体的不平衡影响、湿度效应及泄漏和反扩散等影响未作修正等,实验研究了一种用RAD7型氡气检测仪快速测定土壤、岩石、建材和尾矿等介质表面氡析出率的方法.通过在测量氡析出率参考装置上的验证,表明对上述影响因素提出的各项修正是必要的,本方法能较准确而快速地测定上述介质表面的氡析出率.

| Abstract: | In order to solve problems existing in current measuring methods for radon exhalation rate(such as the effect of unequilibrium Radon and its progeny,humidity effect,leak and back-diffusion effect,etc.),based on the principle of surveying radon and its progeny in the medium surface,a rapid and accurate method for measuring radon exhalation rate taking advantage of the RAD7 radon detector was established.Throught the verification by the test on the standard radon flux facility,it shows that the procedure of this method including the data processing is necessary and successful. |
