electromagnetic fields

Nonionizing electromagnetic fields range from less than 1 cycle/second (Hertz, or Hz) for DC power lines up to 100 GHz for long-distance microwaves and radar.

There is public concern that residential exposure to ambient 50- to 60-Hz magnetic fields is a health threat that may contribute to an increased incidence of leukemia in children. However, epidemiologic studies have failed to establish a significant relationship between residential electromagnetic fields and an increased incidence of childhood leukemia except perhaps at very high exposures.

Occupational exposures at higher levels have also not consistently been associated with an increased risk of leukemia, brain cancer, breast cancer, or neurodegenerative disease.

Animal studies have not provided any evidence for a causal relationship between exposure to electromagnetic fields and brain cancer.

Thus, cell phone users can be assured that going wireless is unlikely to predispose them to the development of brain tumors.
