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

devices 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 cancercausing 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 devices, so we do not

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

devices 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 device RF

exposures. However, none of the studies can answer questions about long-term

exposures, since the average period of device use in these studies was around three


5. What research is needed to decide whether RF exposure

from wireless devices poses a health risk?

A combination of laboratory studies and epidemiological studies of people

actually using wireless devices would provide some of the data that are needed.

Lifetime animal exposure studies could be completed in a few years. However,

very large numbers of animals would be needed to provide reliable proof of a

cancer promoting effect if one exists. Epidemiological studies can provide data

that is directly applicable to human populations, but ten or more years follow-up

may be needed to provide answers about some health effects, such as cancer.

This is because the interval between the time of exposure to a cancercausing

agent and the time tumors develop — if they do — may be many, many years. The

interpretation of epidemiological studies is hampered by difficulties in measuring

actual RF exposure during day-to-day use of wireless devices. Many factors affect

this measurement, such as the angle at which the device is held, or which model of

device is used.
