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 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 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 well within the FCC’s
compliance limits.
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
