They found no association between overall brain cancer risk and cell-phone usage. Compared with the control group, cell-phone users had more than double the risk of developing the tumor. A hazard for rats Dr. Henry Lai, a University of Washington bioengineer, has published a number of studies indicating the radiation emitted by cell phones may pose a health hazard. In research done on rats, Lai showed that cells in the brain had suffered genetic damage after exposure to the same strength and kind of radiation emitted by cell phones. Other studies have documented DNA damage caused by cell phone signals.
Cancer is thought to be prompted by genetic damage.
In January's edition of the journal Bioelectromagnetics, the UW scientist published another study on rats that tested spatial memory. All rights reserved.
