This is not to imply that people who voice concerns about cell phone radiation are misguided.
Happily, hair dye and cell phone radiation are not likely connected to breast cancer, the IOM team repots.
FORBES: Environmental Risks For Breast Cancer: What You Need To Know
But it does provide a tacit sanction of cell phone radiation fears by a recognized authority, an important social signal.
The effect of increased brain activity in children because of cell phone radiation is another area yet to be studied.
Despite years of research, there's still no conclusive proof cell phone radiation causes cancer and other health problems in the brain.
Result: The five shields did virtually nothing to reduce the brain's exposure to cell phone radiation, says Donald Mays, the institute's technical director.
His willingness to misrepresent my work is of a piece with his inability to tolerate any critical or nuanced discussion of cell phone radiation.
The problem, he notes, is that public fears about cell phone radiation do not appear to be supported by the preponderance of scientific research.
The possible health risk of cell phone radiation is a hot-button topic for many people, and this controversy is definitely not just about science.
And the new research joins numerous previous studies on cell phone radiation that have been unable to definitively prove or disprove cell phones' safety.
But these new findings don't tell us whether activating the cells artificially, in this case by cell phone radiation, will have a negative effect on health.
Manufacturers of many popular cell phones already warn consumers to keep their device away from their body and medical experts say there other ways to minimize cell phone radiation.
While the world waits for more research to be conducted, consumers can take steps to limit cell phone radiation exposure by using the speakerphone or a wired earpiece to make calls.
The study was praised as offering "an important insight into potential effects of cell phone radiation on the human brain" by Renee Sharp, director of the Environmental Working Group California office.
Volkow says that since she began working with the National Institutes of Health researching the impact of cell phone radiation, she always uses a wired earpiece when talking on her cell phone.
Here's some reassuring medical news: Recent studies in the New England Journal of Medicine and the Journal of the American Medical Association have found no connection whatsoever between cell phone radiation and brain cancer.
The findings of the study, which examined the subjects during just one 50-minute exposure, raise a key question, the researchers said: What, if any, are the long-term consequences of repeated increased brain activity due to exposure to cell phone radiation?
There is so much confusion surrounding the question of possible danger from cell phones, that the FCC announcement raises questions about what sort of review will be conducted, how much credibility it will have, and whether it will come to grips with the varied and difficult scientific evidence bearing on the potential health effects of cell phone radiation.
The fact is that the scientific jury is still out on the effects of cell phone-emitted radiation.
Result: All five shields did virtually nothing to lower a cell phone's radiation exposure to the brain, says Donald Mays, the institute's technical director.
This ordinance amends the city's controversial Cell Phone Right to Know Act, a similar but more cumbersome law passed last year that required cell phone retailers to post and distribute radiation information for every make and model of cell phone they sell.
The type of radiation coming out of a cell phone is called non-ionizing.
These have been reviewed critically by the International Commission on Non-Ionizing Radiation Protection, which found no convincing evidence of a link between cell phone use and the occurrence of brain tumors.

Moulder, a radiation biologist at the Medical College of Wisconsin who has been a consultant to the cell phone industry.
"The human brain is sensitive to the electromagnetic radiation emitted by cell phones, but for the brain to be impacted, the cell phone has to be close to the head, " Volkow said.
