1. Turning the Phone on and off

SAFETY

The 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 handheld

wireless phones with built-in antennas, often called

"cell", "mobile", or "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 FCC safety

guidelines that were developed with the advice of the

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

socalled "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 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
