Residential exposure to magnetic fields and acute lymphoblastic leukemia in children
Article Abstract:
There appears to be no significant link between exposure to electromagnetic fields and acute lymphoblastic leukemia (ALL) in children. Researchers measured the magnetic field in the bedrooms of 638 children with ALL and 620 healthy children over a 24-hour period and also in other parts of the house. In many cases, they also measured magnetic fields in the house where the family had lived during the mother's pregnancy. Technicians also estimated exposure from a visual inspection of power lines near the home. There was no association between ALL and exposure to high-intensity fields by any of these measures.

Cellular-telephone use and brain tumors
Article Abstract:
The use of a cellular telephone did not increase the risk of brain cancer in a study of 782 patients with a brain tumor and 799 patients admitted to a hospital for some other medical condition. However, more research is needed to determine whether long-term, extremely heavy use of a cell phone might increase the risk of brain cancer.

Cellular telephones and brain tumors
Article Abstract:
It seems very unlikely that cellular telephones substantially increase the risk of brain cancer. The radio frequencies used by cell phones are not carcinogenic, and they do not cause biological tissue to become hot. Several studies have shown no risk, but research must focus on long-term use since cancer can take 20 years to develop.
