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
