The National Institutes of Health participates in some interagency working group

activities, as well.
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 subject of the safety questions

discussed in this document.

3. What kinds of phones are the subject of this update?

The term wireless phone refers here to hand-held wireless phones with built-in antennas,

often called cell mobile or PCS phones. These types of wireless phones can expose the

user to measurable radio frequency energy (RF) because of the short distance between

the phone and the user’s head. These RF exposures are limited by Federal

Communications Commission safety guidelines that were developed with the advice of

FDA and other federal health and safety agencies. When the phone is located at greater

distances from the user, the exposure to RF is drastically lower because a person's RF

exposure decreases rapidly with increasing distance from the source. 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 energy (RF) 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
