For more accurate assessments of the occupational exposure to radon for miners, the individual monitoring was conducted by using an improved passive integrating (222)Rn monitor. A total of 120 miners in 3 different kinds of mines were monitored throughout a year. The results showed that the individual exposure to radon significantly varied with types of mines and work. Compared with the exposure to coal miners, the exposure to copper miners was much higher. Furthermore, it was found that the exposure might be overestimated if the environmental (222)Rn monitored by the passive integrating monitors was used for assessment. The results indicate that the individual monitoring of radon is necessary for an accurate assessment of radon exposure to miners, and radon exposure to non-uranium miners should also be assessed from the viewpoint of radiation protection.
为更准确地评估矿工的职业氡暴露情况，采用改进的被动式积分（²²²Rn）监测仪进行个体监测。全年共监测了3种不同类型矿山的120名矿工。结果表明，个体氡暴露量因矿山类型和工作不同而有显著差异。与煤矿工人相比，铜矿工人的暴露量要高得多。此外，研究发现，如果用被动式积分监测仪监测的环境（²²²Rn）用于评估，暴露量可能会被高估。结果表明，对矿工进行氡的个体监测对于准确评估氡暴露是必要的，并且还应从辐射防护的角度评估非铀矿矿工的氡暴露情况。
