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 predisposed 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 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 phone RF

exposures.

However, none of the studies

can answer questions about

longterm exposures, since the

average period of phone use in

these studies was around three

years.

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
