The 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. The FCC relies on the FDA and other health agencies for safety questions about wireless phones. The FCC also regulates the base stations that the wireless phone networks rely upon.

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.

The National Institutes of Health participates in some interagency working group activities, as well. The 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.
The FCC relies on the FDA and other health agencies for safety questions about wireless phones.
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

These RF exposures are limited by FCC safety guidelines that were developed with the advice of the FDA and

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
