wireless phones to notify users of the health hazard and to repair, replace or 
recall the phones so that the hazard no longer exists.
Although the existing scientific data do not justify FDA regulatory actions, FDA 
has urged the wireless phone industry to take a number of steps, including the 
following:
Ⅲ
Support needed research into possible biological effects of RF of the 
type emitted by wireless phones; 
Ⅲ
Design wireless phones in a way that minimizes any RF exposure to the 
user that is not necessary for device function; and 
Ⅲ
Cooperate in providing users of wireless phones with the best possible 
information on possible effects of wireless phone use on human health 
FDA belongs to an interagency working group of the federal agencies that have 
responsibility for different aspects of RF safety to ensure coordinated efforts at 
the federal level. The following agencies belong to this working group:
Ⅲ
National Institute for Occupational Safety and Health
Ⅲ
Environmental Protection Agency
Ⅲ
Federal Communications Commission
Ⅲ
Occupational Safety and Health Administration
Ⅲ
National Telecommunications and Information Administration
The National Institutes of Health participates in some interagency working 
group activities, as well.
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. 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.
