The term "wireless phone" refers here to hand-held wireless phones with
built-in antennas, often called "cell," "mobile," or "PCS" phones. These
types of wireless phones can expose the user to measurable
radiofrequency energy (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 telephone
wiring in a house, typically operate at far lower power levels, and thus
produce RF exposures far below the FCC safety limits.
4. 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 radiofrequency 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 the 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 the 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, glioma,
meningioma, or acoustic neuroma, tumors of the brain or salivary gland,
leukemia, or other cancers. None of the studies demonstrated the
