Considerations About Induction Heating And The Effects Of Low Fre-
quency Electric And Magnetic Fields
The following is a quotation from the General Conclusions Section of the
U.S. Congress, Office of Technology Assessment, Biological Effects of
Power Frequency Electric & Magnetic Fields – Background Paper,
OTA-BP-E-53 (Washington, DC: U.S. Government Printing Office, May
1989): “. . . there is now a very large volume of scientific findings based
on experiments at the cellular level and from studies with animals and
people which clearly establish that low frequency magnetic fields can
interact with, and produce changes in, biological systems. While most of
this work is of very high quality, the results are complex. Current scientif-
ic understanding does not yet allow us to interpret the evidence in a
single coherent framework. Even more frustrating, it does not yet allow
us to draw definite conclusions about questions of possible risk or to of-
fer clear science-based advice on strategies to minimize or avoid
potential risks.”
To reduce magnetic fields in the workplace, use the following proce-
dures:
1.
Arrange output cable to one side and away from the operator.
2.
Do not coil or drape output cable around the body.
3.
Keep power source and cable as far away from the operator as
practical.
About Pacemakers:
The above procedures are also recommended for pacemaker wearers.
Consult your doctor for complete information.
