塑料热合机始用于60年代初期,至今已有20多年历史。因为使用方便,加热快而均匀,在塑料制品行业中得到广泛应用。但由于对高频电磁波对人体的危害认识不足,出厂时未考虑到屏蔽装置,影响了工人的健康,且电磁波的干扰,影响了无线电导航等,特别是对电视的干扰。为进一步了解目前此类设备高频电磁波泄漏情况及对工人健康的影响,对照国内外标准进行探讨,以便为国内制订卫生标准提供一些参考依据,现将调查结果报道如 Plastic heat sealing machine is used for the early 60s, has been more than 20 years of history. Because of easy to use, fast and uniform heating, the plastic products industry has been widely used. However, due to the lack of awareness of the dangers of high-frequency electromagnetic waves on the human body, the shielding device was not taken into consideration at the factory and the workers’ health was affected. The interference of electromagnetic waves affected the radio navigation and the like, especially the interference to the television. In order to further understand the current high-frequency electromagnetic wave leakage of such equipment and the impact on the health of workers, the domestic and international standards are discussed in order to provide some reference for the development of domestic health standards. The survey results are reported
