With the increased use of electric and electronic equipment in our offices, our daily exposure to electromagnetic fields has become increasingly complex due to the great variety of the frequency content of the fields. Today focus has shifted from monitors as the dominating sources of electromagnetic fields to other electronic equipment, cabling, nearby substations, power lines and stray currents in buildings. In the last 5 years wireless communication has become common in our offices. These devices use radio frequency waves to communicate and are therefore sources of radio frequency fields in our offices. To a certain degree, they all add to the complicated issue of the extensive field frequencies found in offices. The exposure of office workers is generally considered to be low and not in conflict with the existing guidelines, but if a precaution approach is applied there are a number of measures that can be taken to reduce the electromagnetic fields in offices in order to obtain a good electrical environment.
随着我们办公室中电气和电子设备使用的增加，由于电磁场频率成分的多样性，我们日常接触的电磁场变得日益复杂。如今，关注点已从作为电磁场主要来源的显示器转移到其他电子设备、布线、附近的变电站、输电线以及建筑物中的杂散电流。在过去五年中，无线通信在我们办公室已变得很普遍。这些设备利用射频波进行通信，因此是我们办公室中射频场的来源。在一定程度上，它们都加剧了办公室中广泛存在的场频率这一复杂问题。办公室工作人员的接触通常被认为较低，且与现有准则不冲突，但如果采取预防措施，可以采取一些措施来降低办公室中的电磁场，以获得良好的电气环境。
