thousands of times lower than those they can get from wireless
phones. Base stations are thus not the primary subject of the
safety questions discussed in this document.
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 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 phones 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.
