典型非铀矿山工人氡危险认知研究

目的 调查非铀矿山工人对氡所致健康危害的认知水平及影响因素。方法 采用当面填写调查表或询问方式调查了9个省区24个矿山的2836名矿工。结果 13.3%的矿工知晓氡,其中,29.0%的人知道氡的来源,8.5%的矿工对氡危害有一定认识,仅有1.8%的矿工对氡致健康危害有正确认知。在影响非铀矿山工人对氡致健康危害正确认知水平的因素中,受教育程度与氡认知水平正相关;正式职工对氡的认知水平优于临时雇用工人;性别、年龄、从事现工作的工龄等因素对氡认知水平没有明显影响;不同省区及矿山的氡认知水平不同。结论 我国非铀矿山矿工对氡危险认知水平较低,应进一步落实并规范《职业病防治法》规定的职业危害告知义务。

Perception of radon risk in typical non-uranium mines in China

Objective To investigate the perception of risk from occupational exposure to radon among the non-uranium miners in China, and to explore its major influence factors.Methods 2836 workers from 24 mines in 9 provinces/regions were interviewed. Logit regress analysis was used to identify the major influence factors.Results Among the interviewed mine workers, 13.3% of them had heard of radon, 29.0% of those miners who had heard of radon had some knowledge of the source of radon. Only 1.8% of the investigated mine workers had correct perception of health risk resulted from exposure to radon. The major factors to influence the radon risk perception included education degree and type of employment, perception was lower in those miners with low education or temporally employed. Perception level differed by province/regions and mines. Sex, age, and working length of the current job were not the main factors to influence the risk perception.Conclusions The perception of radon risk resulted from occupational exposure among the Chinese non-uranium mine workers is low. More works are needed to effectively implement notification of occupational health hazards, which is stipulated by Chinese law on prevention and control of occupational disease, and one of the important factors in radon mitigation in mines.
