现将对我市六个系统(12个单位)的高频作业场所的劳动卫生学调查及对从业工作人员健康体检结果报告如下: (一)对象与方法:主要选择广播通讯、高频焊接及塑料热合等部门的高频设备进行电磁场强度测定,并对233名高频作业工人及67名对照组人员进行全面查体。所查高频设备大部为五十或六十年代产品,工作频率为中短波频段,工作场所较宽敝,通风和气象条件较好。使用浙江省兴安江无线电厂生产的EF-J高频近区场强仪,按高频电磁场强度测定规范进行测定。(二)结果:(1)电磁场强度测定:测了12个工厂(电台),32台高频设备,获得了120个数据(电场63个,磁场57个),电场强度波动范围为10-600伏/米,磁场波动范围为1-22安/米。体检结果:神经衰弱症候群、性功能
Now on the city six systems (12 units) of the high-frequency workplaces of labor hygiene survey and health workers on the health examination results reported as follows: (a) objects and methods: the main choice of radio communications, high frequency welding and Plastic heat sealing and other departments of high-frequency equipment for the determination of electromagnetic field strength, and 233 high-frequency working workers and 67 control group personnel a comprehensive examination. The majority of the high-frequency equipment examined were those manufactured in the 1950s and 1960s. The working frequency was in the short-wave band, the workplace was wider, and the ventilation and weather conditions were better. The EF-J high frequency near field strength meter produced by Xing’anjiang Radio Factory in Zhejiang Province was measured according to the high frequency electromagnetic field strength measurement standard. Results: (1) Measurement of electromagnetic field strength: 12 factories (radio stations) and 32 high-frequency equipments were measured and 120 data (63 electric fields and 57 magnetic fields) were measured. The fluctuation range of electric field intensity was 10-600 V / m, magnetic field fluctuations in the range of 1-22 A / m. Physical examination results: Neurasthenia syndrome, sexual function
