"Davis noted during her talk that many scientists have dismissed the idea that exposure to radio-frequency electromagnetic radiation may pose health threats. Unlike X-rays and other forms of “gamma radiation,” radio waves are non-ionizing – they do not directly break chemical bonds within molecules such as DNA.
But DNA is damaged indirectly by cell phone transmissions, according to Davis. Within cells, she said, “There are alterations of fundamental processes by pulsed signals from cell phones.” For instance, exposure can trigger production of harmful production of oxygenating free-radical molecules. Davis presented research showing that radiofrequency electromagnetic radiation does indeed damage DNA.
Experiments also find evidence for disruptions to the cell cycle, through which cells divide and grow, and a decrease in the ability of cells to repair DNA, Davis said.
Davis noted the role of epidemiologic studies in demonstrating the health hazards of tobacco and asbestos. She said it is a mistake to insist on a demonstration of a biological mechanism of harm for proof. Epidemiologic evidence plus a biologically plausible mechanism should be sufficient evidence to act upon, Davis said, and such evidence already exists."
"Cancers may be triggered decades before they are diagnosed. Excess brain cancers among survivors of atomic bombs dropped on Japan did not become apparent until more than 40 years later, Davis said. Children, whose cells and tissues are still developing quickly, may be especially vulnerable – also evidenced by the high incidence and early onset of breast cancers among atomic bomb survivors"
