The 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:

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 builtin

short distance between the phone and the user’s head. These RF exposures are

distances from the user, the exposure to RF is drastically lower because a person’s
