This book examines the health effects of exposure to static
electric and magnetic fields found in selected industries, such as
medical facilities with magnetic resonance imaging (MRI),
high-energy physics research facilities and some transportation
systems. To date, research on their health effects lags far behind
the rapid advances in technology. Electric and magnetic fields are
generated by natural phenomena such as the Earth s magnetic field,
thunderstorms, and by man-made sources that use electricity. When
such fields do not vary with time they are referred to as static.
For static electric fields, studies carried out to date suggest
that the main effect is discomfort from electric discharges to the
body. For static magnetic fields, acute effects are only likely to
occur when there is movement of a person in the field. For example,
a person moving within a relatively high field can experience
sensations of vertigo and nausea, and sometimes a metallic taste in
the mouth and perceptions of light flashes. Although only
temporary, such effects may have a safety impact for workers
executing delicate procedures, e.g. surgeons performing operations
within MRI units. Even when at rest, a person will experience
internal body movement, such as blood flow or heart beat. When
placed within a high magnetic field, electrical fields and currents
are generated around the heart and major blood vessels that can
impede the flow of blood. Possible effects range from minor changes
in heartbeat to an increase in the risk of abnormal heart rhythms
that might be life threatening."
