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 answer 
questions about long-term exposures, since average period 
of phone use in these studies was around three years.
