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 Radio Frequency (RF) energy
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 do not 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 existence of any harmful health effects
from wireless phone RF exposures. However, none of the studies can
answer questions about long-term exposures, since the average period of
phone use in these studies was around three years.
5. What research is needed to decide whether RF exposure from
wireless phones poses a health risk?
A combination of laboratory studies and epidemiological studies of people
actually using wireless phones would provide some of the data that are
needed. Lifetime animal exposure studies could be completed in a few
