3. What are the results of the research done

already?

The research conducted 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 it is largely unknown what the

results of such studies mean for human health and

safety. Three large epidemiology studies have been

published since December 2000. These studies

investigated possible associations between the use

of wireless phones and primary brain cancer (glioma,

meningioma, acoustic neuroma, other brain tumors,

and salivary gland tumors), leukemia, or other types

of cancer. None of the studies demonstrated the

existence of any harmful health effects from wireless

phone RF exposures. However, none of the studies
