Tritium is one of several radioactive nuclides routinely monitored in and around CANDU (CANada Deuterium Uranium) power reactor facilities. Over the last ten years, passive samplers have replaced active sampling devices for sampling tritiated water vapor in the workplace at many CANDU stations. The potential of passive samplers for outdoor monitoring has also been realized. This paper presents the results of a 1-y field trial carried out at all five Canadian CANDU reactor sites. The results indicate that passive samplers can be used at most sampling locations to measure tritiated water vapor in air concentrations as low as 1 Bq m-3 over a 30-d sampling period. Only in one of the five sampling locations was poor agreement observed between active and passive monitoring data. This location, however, was very windy and it is suspected that the gusty winds were the source of the discrepancies observed.
氚是坎杜（加拿大重水铀）动力反应堆设施内部及周边常规监测的几种放射性核素之一。在过去十年中，被动式采样器已取代主动采样设备，用于许多坎杜电站工作场所中氚化水蒸气的采样。被动式采样器用于户外监测的潜力也已得到认可。本文介绍了在加拿大所有五个坎杜反应堆站点进行的为期1年的现场试验结果。结果表明，在30天的采样期内，被动式采样器可用于大多数采样地点，以测量空气中低至1 Bq m-3的氚化水蒸气浓度。在五个采样地点中，只有一个地点的主动监测数据与被动监测数据之间存在较大差异。然而，该地点风很大，怀疑阵风是观察到差异的原因。
