For Your 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 Radio Frequency (RF) energy

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 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 (RF) energy 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 do not know with certainty what the
