随着我国电子工业的发展,以及新技术在冶金工业上的应用,高频冶炼所致电磁波对人体产生的影响逐渐引起人们的重视。为了掌握高频电磁场对人体健康的影响,以保证操作工人的安全与健康,于1975年冬我们对某厂从事这种作业的137名工人进行了现场高频电磁场场强测定,并作了一系列医学检查,将结果报告如下, 一般情况 共检查男性工人96名,平均年龄31.9岁,平均工龄6.28年;女性工人41名,平均年龄31.9岁,平均工龄6.03年,男女工人的年龄与工龄均无显著差别(P>0.05)。 作业场所电磁波的振荡频率为2.2～2.6兆周。用射频电磁场测定仪作水平距离测定结果,从5厘米到100厘米的平均电场强度均超过最大容许参考标准(20伏/米)以上。平均磁场强度在最大容许参考标准(5安/米)以内。
With the development of China’s electronics industry and the application of new technology in the metallurgical industry, the impact of electromagnetic waves caused by high-frequency smelting on the human body gradually attracts people’s attention. In order to grasp the impact of high-frequency electromagnetic fields on human health so as to ensure the safety and health of operating workers, we conducted a field high-frequency electromagnetic field measurement of 137 workers engaged in such operations in a factory in the winter of 1975, A total of 96 male workers were examined, with an average age of 31.9 years and an average length of service of 6.28 years. 41 were female workers, with an average age of 31.9 years and an average length of service of 6.3.03. Both the age and length of service for both men and women No significant difference (P> 0.05). Operating site electromagnetic wave oscillation frequency of 2.2 ~ 2.6 trillion weeks. As a result of the horizontal distance measurement using a radio frequency electromagnetic field measuring instrument, the average electric field strength from 5 cm to 100 cm exceeded the maximum allowable reference (20 V / m). The average magnetic field strength is within the maximum allowable reference (5 A / m).
