摘要/Abstract

摘要： 目的鉴于我国稀土矿山作业环境中存在职业危害因素,研发一套能够同步监测矿尘与高氡个体暴露的协同技术设备。方法分析稀土矿山呼吸性粉尘与高氡个体暴露监测的技术需求,提出合适的研发思路与关键研制要点。结果采用双层滤网技术实现呼吸性粉尘BMRC曲线分离采样,结合抽气装置与玻纤滤膜,并利用CR39固体核径迹探测器完成对氡钍射气子体所致辐射剂量的定量测定。结论该设备的研制有望同时实现对稀土矿山开采中两种主要职业危害因素(显著增加肺部及相关器官癌瘤风险)的同步采样与分析,为职业性肺癌协同作用效应的研究奠定了前期技术基础。

Abstract: Objective An integrated monitoring technology and supporting equipment for personal exposure to respirable dust and high levels of radon were investigated, given the severe occupational hazards present in mine operations in China. Methods By analyzing and summarizing the technical requirements for personal exposure monitoring of respirable dust and high radon, suitable research approaches and key development points were identified. Results The BMRC curve-based separation sampling for respirable dust was achieved through a dual-layer filter technique. Radiation dose from radon and thoron progeny was quantified using CR39 solid-state nuclear track detectors, while a suction device combined with glass fiber filters was used for dust sampling. Conclusions The development of this equipment may enable simultaneous sampling and analysis of two major occupational hazards that contribute to an elevated risk of lung cancer and other associated cancers, and has laid important technical groundwork for examining the synergistic effects of occupational hazards to lung cancer.

Key words: respirable dust, radon progeny and thoron progeny, personal sampling
