Many studies report small increases in the rate of leukemia or brain cancer in groups of people living or working in high magnetic fields. Other studies have found no such increases. The most important data come from six recent studies of workers wearing EMF monitors to measure magnetic fields.
All but one study found significantly higher cancer rates for men with average workday exposures above 4 milligauss. However, the results of these studies disagree in important ways such as the type of cancer associated with EMF exposures. So scientists cannot be sure whether the increased risks are caused by EMFs or by other factors. A few preliminary studies have also associated workplace EMFs with breast cancer, and one study has reported a possible link between occupational EMF exposure and Alzheimer s disease.
The data from all of these studies are too limited for scientists to draw conclusions. However, a national research effort is under way, and more study results are expected in a few years.
The National Institute for Occupational Safety and Health (NIOSH) and other government agencies do not consider EMFs a proven health hazard. Because some studies have associated high magnetic field exposures with increased cancer risks,
the government will continue studying EMFs. While research continues, concerned workers and employers might consider the following simple, inexpensive measures for reducing EMF exposures:
Inform workers and employers about possible hazards of magnetic fields.
Increase the worker's distance from the EMF source. Since magnetic fields often drop off dramatically within about 3 feet of the source, workers can stand back from electrical equipment, and work stations can be moved out of the 3-ft range of stronger EMF sources.

Because only small amount of people are exposed to high magnetic fields, it is difficult to do large scale studies. When I was working there and later at a Aluminium plant in Texas, I did not see any health group doing health studies. It is a simple logic, some old people have difficulty grasping....
If you want to expose to high magnetic fields....go ahead....
