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.
在南华大学氡实验室进行了与钍射气-氡甄别监测仪的比对测量。比对结果表明，大多数监测仪（包括参与者A和参与者B的固体核径迹探测器、RAD7和RTM2100连续监测仪）在钍射气与氡的比例范围较宽时，钍射气-氡甄别性能良好。RAD7、RTM2100与参考仪器之间的钍射气测量结果存在很大差异。对这些差异原因的讨论揭示了改进监测仪校准、钍射气源制作的必要性以及更多国际比对的必要性。
