矿井作业场所中呼吸尘与氡子体同时监测的方法研究

矿井作业面的粉尘与氡子体是危害工人健康的两在重要因素。有效地监测空气中的粉尘怀氡子体是工业卫生学者一直关心的课题，而如何有效地同时监测呼吸尘与氡子体更受到人们的关注。介绍了一种同时监测呼吸尘浓度与氡子体α潜能浓度的方法，该方法是将热释光探测元件组装在呼吸尘个体采样器中，使热释光元件受到与呼吸尘一起被采集在滤膜上的氡子体的放射照射。采样结束后，分别测出滤膜上的粉尘量及热释光探测元件的热释光计数，即可

Development of a Method for Simultaneous Monitoring of Respirable Dust and Radon Daughters in Mine

Dust and radon daughters are two major hazards to miners.It has been an interesting subject for industrial hygienists to monitor the dust and radon daughter aerosols effectively.More attention has been paid to develop a method which could simultaneously monitor radon daughters and the dust.A new method is introduced,in which the thermoluminescent detector(TLD) is set in the respirable dust sampler,so that the detector could be radiated by radon daughter aerosols sampled on the filter along with the respirable dust.After sampling,the dust masses on filter and the radiation counts of the TLD could be measured respectively.The mass concentration of dust and potential energy concentration of radon daughters may thus be obtained at the same time.The operations and monitoring results by this method were given and the error control was discussed.Application showed that the method is feasible and practicable with satisfactory results.
