The paper presents the results realised simultaneously by two different and independent systems of measurement of an assessment of miners' exposure to radon daughter products which naturally occur in the air of mines. The first one, called the Air Sampling System (ASS), was based on the field monitoring of radon progeny in air, the second one, called the Individual Dosimetry System (IDS), was based on the individual dosimeters worn by miners. Experimental comparison of these two systems has been conducted for six years in eleven Polish underground metal-ore mines. This study reveals that no correlation exists between the concentration and annual miners' exposures evaluated by the ASS and IDS. The ratio ASS/IDS for mine population varies from 11.0 to 0.14 in respect of annual concentration means, and in respect to annual exposures, this ratio varies from 4.5 to 0.14. The conclusion to be drawn from six years' observation and comparison of both systems is that correct and true evaluation of miners' exposure to radon progeny can be made only by the use of the Individual Dosimetry System, since the Air Sampling System is too sensitive and too dependent on the Strategy of sampling and its radiation.
本文介绍了两种不同且独立的测量系统同时得出的结果，这两种系统用于评估矿工接触矿井空气中天然存在的氡子体的情况。第一种称为空气采样系统（ASS），基于对空气中氡子体的现场监测；第二种称为个人剂量测定系统（IDS），基于矿工佩戴的个人剂量计。在波兰的11个地下金属矿中，对这两种系统进行了为期六年的实验比较。这项研究表明，ASS和IDS评估的浓度与矿工年度暴露量之间不存在相关性。就年度浓度均值而言，矿井人群的ASS/IDS比值在11.0至0.14之间变化；就年度暴露量而言，该比值在4.5至0.14之间变化。从对这两种系统进行的六年观察和比较中得出的结论是，只有使用个人剂量测定系统才能对矿工接触氡子体的情况进行正确和真实的评估，因为空气采样系统过于敏感，且过于依赖采样策略及其辐射情况。
