| 摘 要： | 利用开环方式测量氡析出率,不需要考虑泄漏和反扩散的影响,计算简单.但是开环方式测量氡析出率测量中有一个很重要的参数是泵的流率,对于高析出率介质,采用较高的流率,可以减小集氡罩内氡浓度达到恒定的时间,提高测量效率；对于低析出率介质,采用较高的流率,会导致集氡罩内的氡浓度值偏低,统计涨落较大,甚至会使得集氡罩内的氡浓度值难...

| Abstract: | The calculation of measuring radon exhalation rate in open-loop is simple,without considering the effects of leakage and back-diffusion.But the pump flow rate is a very important parameter in the measurement.If the exhalation rate of the medium is high,the time for the radon concentration in the chamber becomes constant decrease while the pump flow rate is high.The measurement efficiency will be improved.If the exhalation rate of the medium is low,the radon concentration in the chamber will be very low for ... |
