关于个人粉尘采样器 随着工业的发展,粉尘的危害性越来越大,人们应用各种各样的方法来认识它,评价它,而粉尘的个人采样法是国外很多工业卫生学者重视的一种方法。要实施个人采样法,必须研制个人采样器。 1960年Sherwood首先研制了测定放射性粉尘的个人采样器,其流量为400立方厘米/分,以一周为单位测定作业者呼吸带的浮游粉尘浓度,用干电池为动力带动小型隔板的抽气泵。以后,Crithow研究了流量为3升/分,用于一个工作日采样的标准型个人粉尘采样器,
About Personal Dust Sampler With the development of industry, dust is more and more harmful. People use a variety of methods to recognize it and evaluate it. The personal sampling method of dust is one of the most important foreign industrial hygienists Kind of method. To implement personal sampling method, we must develop a personal sampler. 1960 Sherwood first developed a personal sampler for the determination of radioactive dust with a flow rate of 400 cc / min. The concentration of suspended dust in the breathing zone of the operator was measured in a week, and the suction pump was driven by a dry battery. Later, Crithow studied a standard personal dust sampler with a flow rate of 3 liters / minute for sampling on a working day,
