Up to now, several different timetables have been proposed for thoron ((220)Rn) measurements by using the Lucas scintillation cell. In this study, based on the measuring principle, the uncertainty of the measurements was theoretically studied by using a self-developed simulation program. The results showed that a measuring timetable of 1-min consecutive counting lasted for 10 times was an optimal routine for (220)Rn measurements. Compared with the previously proposed timetables, the new measuring timetable could reduce the uncertainty of (220)Rn measurements by >19 %.
到目前为止,已经提出了几种使用卢卡斯闪烁室测量钍射气((220)Rn)的不同时间表。在本研究中,基于测量原理,使用自行开发的模拟程序从理论上研究了测量的不确定性。结果表明,连续计数1分钟持续10次的测量时间表是(220)Rn测量的最佳常规方法。与先前提出的时间表相比,新的测量时间表可以将(220)Rn测量的不确定性降低超过19%。
