With nearly a billion cell phone users worldwide, it is difficult to find anyone — on campus or elsewhere — without one. The prevalence of wireless users, however, shows that many are not heeding the increasing concern about the potentially harmful effects of cell phones including the damage cell phones may do to DNA in brain cells.
UW bioengineering professor Henry C. Lai has focused much of his research on trying to understand the way electromagnetic radiation emitted from these wireless devices affects the human body.
“What people don’t realize [when they use cell phones] is that they are irradiating themselves,” Lai said.
His studies have mainly consisted of exposing lab rats to microwave radiation similar to that emitted by cell phones, and then examining the rats’ brain cells to determine if DNA was damaged.
Any damage sustained by the DNA signifies a break in the body’s genetic code and the occurrence of a potential mutation, which could lead to tumors and cancer.
