3. What kinds of devices are the subject of this update?
The term 'wireless device' refers here to handheld wireless devices with built-in
antennas, often called ' c ell' , 'mobile' , or 'PCS' devices. These types of wireless devices
can expose the user to measurable radiofrequency energy (RF) because of the
short distance between the device and the user' s head. These RF exposures are
limited by FCC safety guidelines that were developed with the advice of the FDA
and other federal health and safety agencies. When the device 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 ' c ordless devices, ' which have a base unit connected to the device 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) from wireless devices 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 predisposed 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 devices, 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 devices 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
existence of any harmful health effects from wireless device RF exposures.
However, none of the studies can answer questions about long term exposures,
since the average period of device use in these studies was around three years.
