SAFETY

The so-called “cordless phones,” which have a base

unit connected to the telephone wiring in a house,

typically operate at far lower power levels and thus

produce RF exposures far below the FCC safety

limits.

4. 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 (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 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 long-term exposures, since the

average period of phone use in these studies was

around three years.
