在南华大学氡实验室用Tn-Rn鉴别监测仪进行了比对测量。比对结果表明，绝大多数监测仪（包括参试者A和参试者B的固体核径迹探测器、RAD 7和RTM 2100连续监测仪）的Tn-Rn分辨力在较宽的Tn/Rn比值范围内保持良好。RAD 7、RTM 2100和参考仪器的Tn测量结果存在较大差异。通过对这些差异产生原因的讨论，揭示了在监测仪校准、Tn源制作等方面改进的必要性，以及开展更多国际比对的必要性。
The intercomparison measurements with Tn-Rn discriminative monitor were conducted at the Radon Laboratory of Nanhua University. The intercomparison results indicates that the Tn-Rn discrimination of most monitors (including the solid-state nuclear track detector of participant A and participant B, continuous monitors of RAD7 and RTM2100) keeps well in a wide range of the ratio of Tn to Rn. There are great differences of Tn measurement results among RAD7, RTM2100 and reference instrument. The discussion on the reason of these differences reveals the necessity of improvement on monitor calibration, Tn source make and the necessity of more international intercomparisons.
