A new study suggests that outdated government tests could be putting cell phone users at risk.
The Federal Communications Commission frequently tests the amount of radiation to which cell phone users are exposed.
But according to the Environmental Health Trust, those tests are flawed.
The government uses a plastic mannequin head to test the effects of cell phone radiation.The mannequin, however, is the equivalent of a man with the height measuring 6' 2" and weighting 220 pounds, which represents only 3 percent of the population.
The new report suggests the tests do not accurately report the amount of radiation to which the other 97 percent of the population has been exposed when using cell phones, including women and children.
"The standard for cell phones has been developed based on old science and old models and old assumptions about how we use cell phones, and that's why they need to change," said Dr. Devra Lee Davis, the founder and president of the Environmental Health Trust.
Radiation penetrates 150 percent deeper in a 10-year-old child than it does in an adult male.
The trust is working to find alternative tests. However, both the FCC and independent scientists say that there is no conclusive evidence that cell phone radiation causes cancer.
"There are different types. The radiation from X-rays is ionizing radiation. The kind from cell phones is the same from microwave ovens. There is no good proof that it has caused cancer," said Dr. Richard Besser, ABC News medical editor and the former acting director of the American Centers for Disease Control and Prevention.
Besser says it is still wise for cell phone users to be cautious. He recommends that parents limit the amount of time their children spend on the phone.
He also suggests using hands free devices like a speaker phone whenever possible.
