| Evaluating ELF Exposure |

Public and employee concerns about extremely low frequency
(ELF) exposure has grown
as a result of increased media coverage over the last few years. The issue of
ELF radiation is very controversial. Exposure to electric and magnetic fields (EMFs) depends on the strength of the
ELF fields at the source, the distance from the source, and the duration of exposure.
The 50 to 60 Hz range is of particular interest because it is associated with
electrical power distribution, and equipment utilizing alternating current. The
American Conference of Governmental Industrial Hygienists (ACGIH) has established
occupational exposure guidelines for ELF radiation.

Field Service Memo — Electromagnetic Radiation and How It Affects Your Instruments. OSHA Cincinnati Technical
Center (CTC), (1990, May 20). Provides OSHA compliance officers with basic principles of
electromagnetic (EM) radiation, discusses the effects of radio
frequency interference (RFI) on the operation of industrial hygiene
instruments, explains why special isotropic probes are used for making
non-ionizing radiation surveys, and emphasizes the need for special
attention in measuring radio frequency fields.
