CTIA — the Wireless Assn., a U.S. industry group, insists that cellphones pose no danger to users.
“The peer-reviewed scientific evidence has overwhelmingly indicated that wireless devices do not pose a public health risk,” said John Walls, a spokesman for the association. “In addition, there is no known mechanism for microwave energy within the limits established by the FCC to cause any adverse health effects.”
But Morgan, 67, a retired electronics engineer living in Berkeley, scoffed at this position.
“What does ‘no known mechanism’ imply?” he asked. “That’s an anti-scientific statement on its face. All it means is that we don’t know.”
Morgan is a member of the Bioelectromagnetics Society, an organization of scientists and engineers who focus on the effects of electromagnetic fields. He described the International EMF Collaborative as a collection of advocacy groups concerned about electromagnetic radiation.
More than 40 scientists and officials from 14 countries have publicly endorsed the findings of Morgan’s report. They include David O. Carpenter, director of the Institute for Health and Environment at the University at Albany; Jerry L. Phillips, director of the Science Learning Center at the University of Colorado at Colorado Springs; and Dr. Ronald Herberman, director emeritus of the University of Pittsburgh Cancer Institute.
Herberman sent a memo to his staff last year urging them to limit cellphone use and to keep handsets away from their heads whenever possible.
Morgan said the wireless industry and cellphone-danger skeptics base their claims on research showing that radiation emitted by handsets is too weak to heat the tissue in your head and cause tumors to form.
“But what about non-thermal, biological effects resulting from electromagnetic radiation?” he asked.
Morgan pointed out that electromagnetic fields are routinely used to repair bone fractures. Like cellphone radiation, these fields are too weak to heat tissue.
“That tells you that there is also a non-thermal, biological effect from this energy,” Morgan said.
