摘要
This paper presents the investigation of extremely low frequency magnetic fields at electric facilities of a hospital. We conducted 21 measurements (at electric facilities and other areas, for example, in the lobby and in the corridor). The magnetic fields were from 0.2 mu T to 62.0 mu T. The highest value was measured near the main circuit-breaker of the distribution board. Based on the measurements, the magnetic fields can be more than 50 mu T in the technical areas of a hospital, which can cause disturbances in some medical devices.
