(RF) because of the short distance between the phone and the user’s head.
These RF exposures are limited by Federal Communications Commission safety
guidelines that were developed with the advice of FDA and other federal health
and safety agencies. When the phone is located at greater distances from the
user, the exposure to RF is drastically lower because a person’s RF exposure
decreases rapidly with increasing distance from the source. The so-called
“cordless phones” which have a base unit connected to the phone wiring in a
house, typically operate at far lower per levels, and thus produce RF exposures
far below the FCC safety limits.
What are the results of the research done already?
The research done thus far has produced conflicting results, and many studies
have suffered from flaws in their research methods. Animal experiments
investigating the effects of radio frequency energy (RF) exposures
characteristic of wireless phones have yielded conflicting results that often
cannot be repeated in other laboratories. A few animal studies, however, have
suggested that low levels of RF could Accelerate the development of cancer in
laboratory animals. However, many of the studies that showed increased tumor
development used animals that had been genetically engineered or treated with
cancer-causing chemicals so as to be pre-disposed to develop cancer in
absence of RF exposure. Other studies exposed the animals to RF for up to 22
hours per day. These conditions are not similar to the conditions under which
people use wireless phones, so we don’t know with certainty what results of
such studies mean for human health.
Three large epidemiology studies have been published since December 2000.
Between them, the studies investigated any possible association between the
use of wireless phones and primary brain cancer, glaucoma, meningioma, or
acoustic neuroma, tumors of the brain or salivary gland, leukemia, or other
cancers. None of the studies demonstrated the existence of any harmful health
effects from wireless phones RF exposures. However, none of the studies can
