The emission of electromagnetic fields from computer monitors was analysed. The data were compared with the permissible exposure level. EM radiation of chromatic monitors is higher than that of monochromatic ones. The radiation of magnetic fraction is insignificant. Both electric and magnetic fractions of EM radiation, 50 cm away from the monitor, are very low and do not exceed permissible values. It was observed that screen filters were effective in suppressing EM emission only at a short (up to 30 cm) distance from the monitor. At a distance of 50 cm they proved to be ineffective. Metallic-net filters were more effective than glass filters in suppressing EM radiation. It seems that EM fields generated by computer monitors are not harmful to computer operators if the distance is kept in safe limits.
对电脑显示器发出的电磁场进行了分析。将数据与允许暴露水平进行了比较。彩色显示器的电磁辐射高于单色显示器。磁分量的辐射微不足道。在距离显示器50厘米处，电磁辐射的电分量和磁分量都非常低，未超过允许值。据观察，屏幕过滤器仅在距显示器较短（最多30厘米）的距离内有效抑制电磁辐射。在50厘米的距离处，它们被证明是无效的。金属网过滤器在抑制电磁辐射方面比玻璃过滤器更有效。如果保持在安全距离范围内，电脑显示器产生的电磁场似乎对电脑操作员无害。
