“PCS” phones. These types of wireless phones can expose the

user to measurable radiofrequency 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 radiofrequency

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
