It's one of the most contentious debate in tech. Are mobile
phones hazardous to your health? At issue is whether the
electromagnetic radiation emitted by cellphones is dangerous and
even cancer-causing. The verdict is not in, and there are
conflicting scientific signals about the long-term risks to
mobile-phone users. But with more than 5 billion people using
cellphones worldwide, the answer to the medical and scientific
conundrum has global ramifications. "It's unimaginable today
that people will give up cellphones," said Lloyd Morgan, a
retired Silicon Valley electrical engineer who is a senior
research fellow with the Environmental Health Trust, a nonprofit
that researches potential hazards of using mobile phones. His
group advocates taking steps to protect against radiation from
mobile phones. Recent studies about potential dangers from
mobile-phone radiation can be puzzling if not disconcerting to
consumers. The Food and Drug Administration says that scientific
data so far shows no increased health risks
