title: An optimal measuring timetable for thoron measurements by using Lucas scintillation cell.
abstract: 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 %.
