| Abstract |
The frequency spectrum and the magnetic field intensity were measured in the range of 5-500Hz. The magnetic field density at extremely low frequency (ELF) is given in A/m for several VDTs, for locations such as fluorescent lights in offices and laboratories, and for devices such as typewriters, electric kettles, transformers, etc. Biological effects of ELF magnetic fields are described in a separate table. The only significant emission occurs at the power frequency of 60Hz and its harmonics. ELF emissions from VDTs are at least 1000 times less than the magnetic flux densities that were shown to cause potentially hazardous biological effects. |
