NIOSH research on protecting workers from proven and possible EMF health risks focuses on:
- RF (radio frequencies) --including broadcast antennas, induction heaters, and cell telephones
- ELF (extremely low frequencies) --including AC electricity and video display terminals (VDTs)
- Static Magnetic Fields --including DC electricity.
