1990年4月,我们对佳木斯电机厂、煤机厂、拖拉机厂的热处理车间高频作业环境电磁场强度进行了监测,并检查了作业工人的神经机能,结果如下。1 材料与方法 1.1 电磁场强度监测应用“浙2.2型”电磁场测定仪,于高频作业区相当于作业工人的头胸部位检测电磁场强度,并调查防护情况,计算均值。 1.2 调查对象选择电机、煤机、拖拉机厂热处理车间高频作业工人33名为实验组。其中男23名,女10名;年龄为23~35岁,平均27.5岁;工龄4~15年,平均5.7年。选择与实验对象年龄、性别、工龄相同,生活条件相同的无毒害作业工作33名为对照组。
In April 1990, we monitored the electromagnetic field strength of high-frequency working environment of the heat treatment plant of Jiamusi Electric Machinery Works, Coal Plant and Tractor Factory and inspected the neural function of workers. The results are as follows. MATERIALS AND METHODS A. Monitoring of electromagnetic field strength The “Zhejiang 2.2-type” electromagnetic field detector was used to detect the intensity of the electromagnetic field in the head and chest area of a working worker in a high-frequency working area and to investigate the protection and calculate the average value. 1.2 Survey The choice of motor, coal machine, tractor factory heat treatment workshop 33 high-frequency workers for the experimental group. Including 23 males and 10 females; aged 23 to 35 years old, an average of 27.5 years old; length of 4 to 15 years, an average of 5.7 years. The 33 non-toxic work tasks with the same age, gender and length of service as the experimental subjects and the same living conditions were chosen as the control group.
