摘要
Abstract
In this paper,comparisons were made among three methods of measurement（grab measurement,continuous measurement and integrating measurement） and also measurements of different instruments for a radon/thoron mixed chamber.Taking the optimized five-segment method as a comparison criterion,for the equilibrium-equivalent concentration of 222 Rn,measured results of BWLM and 24 h integrating detectors are 31% and 29% higher than the criterion,the results of Wlx, however,is 20% lower;and for 220 Rn progeny,the results of FJ414-142,KF-602D,BWLM and 24 h integrating detector are 86%,18%,28% and 36% higher than the criterion respectively,except that of WLx,which is 5% lower.For the differences shown,further research is needed.关键词
