FDA shares regulatory responsibilities for wireless phones with the Federal

CommunicationsCommission(FCC).AllphonesthataresoldintheUnitedStatesmust

comply with FCC safety guidelines that limit RF exposure. FCC relies on FDA and other

health agencies for safety questions about wireless phones.

FCCalsoregulatesthebasestationsthatthewirelessphonenetworksrelyupon.While

these base stations operate at higher power than do the wireless phones themselves,

the RF exposures that people get from these base stations are typically thousands of

times lower than those they can get from wireless phones.

Base stations are thus not the primary subject of the safety questions discussed in

this document.

What are the results of the research done already?

effects of radio frequency energy (RF) exposures characteristic of wireless phones have

yieldedconicting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 exposures, since

the average period of phone use in these studies was around three years.
