一种同时测量222 Rn、220 Rn的单闪烁室两段法
Simultaneous Measurement of Radon and Thoron Using a Scintillation Cell
摘要
Abstract
A method has been developed for the simultaneous measurement of radon ( 222 Rn) and thoron( 220 Rn) in a mixed environment using a scintillation cell in this paper. The method uses counts from two arbitrary counting intervals from zero time with respect to sampling,establishes two equations with two unknown variables to solve concentrations of radon and thoron,hence,called two-count method( TCM) . The method can be used to esti-mate the radon and thoron concentrations in a mixed environment accurately and quickly, as there is no need to delay the counting to achieve complete decay of thoron.关键词
