目的监测并评价邢台市部分铁矿的氡及其衰变产物水平及对井下矿工的健康影响,从而保障矿工的职业安全。方法按照国家标准规定的方法对氡进行测量。结果邢台市部分铁矿井下氡浓度范围为16.0～385.0Bqm-3,地面工作区室内外分别在17.4～41.2Bqm-3和4.8～25.8Bqm-3之间。结论邢台市部分铁矿氡及其子体浓度处于较低水平属正常本底范围。矿工的生产作业是安全的。
Objective To monitor and evaluate the radon and its decay products in some iron mines of Xingtai City and the health effects on the underground miners so as to ensure the occupational safety of miners. Methods Radon was measured according to the method prescribed by national standards. Results The concentration range of radon in some iron mines in Xingtai City ranged from 16.0 to 385.0 Bqm-3 and the indoor and outdoor work areas were 17.4 to 41.2 Bqm-3 and 4.8 to 25.8 Bqm-3, respectively. Conclusions The concentration of radon and its daughters in some iron ores in Xingtai City is in the normal background at a lower level. Miners’ production operations are safe.
