Extremely low frequency (ELF) fields includes alternating
current (AC) fields and other electromagnetic, non-ionizing radiation from 1 Hz
to 300 Hz. ELF fields at 60 Hz are produced by power lines, electrical wiring,
and electrical equipment. Some epidemiological studies have suggested
increased cancer risk associated with magnetic field exposures near
electric power lines.
The following questions link to information relevant to ELF radiation in the workplace.

Welcome to the California Electric and Magnetic Fields (EMF) Program. California Electric and Magnetic Fields (EMF) Program. Contains
fact sheets in
English and Spanish concerning EMF hazards and solutions in homes and schools.
Also, provides a link to a video that describes how improperly connected
electrical wiring could pose hazards in schools, as well as a school design guidelines
checklist which discusses practical, "no- and low-cost" techniques for
minimizing exposure to magnetic fields in new and remodeled school buildings.
