Electric and Magnetic Fields
Electric and magnetic fields and your health
There has been a fear that electric and magnetic fields (EMF) from power lines in
residential areas may be linked to cancer and other diseases in humans. The National
Institute of Environmental Health Sciences (NIEHS) conducted a six-year research and
evaluation program on EMF connected with power line frequencies. The conclusion was
that the evidence for a risk of cancer and other human disease from the EMF around
power lines is weak.
According to the report, only a weak statistical association exists between EMF exposure
at home and childhood leukemia. A weak statistical association also exists between
chronic lymphocytic leukemia and adults who are employed as electric utility workers,
machinists, and welders.
The NIEHS believes that the probability that EMF exposure is truly a health hazard
is probably small. The weak health associations and lack of any laboratory support
for these associations provide only little scientific support that exposure to EMF
causes any degree of harm.
Many people have concerns that mobile phones and Wi-Fi signals can be a cause of brain
cancer. To date, no evidence of any association exists. Both the World Health Organization
and the EPA believe that any association is unlikely. A close watch will continue
by both organizations.
