Do hands-free kits for
wireless phones reduce
risks from exposure to RF
emissions?
Since there are no known risks
from exposure to RF emissions
from wireless phones, there is
no reason to believe that
hands-free kits reduce risks.
Hands-free kits can be used
with wireless phones for
convenience and comfort.
These systems reduce the
absorption of RF energy in the
head because the phone, which
is the source of the RF
emissions, will not be placed
against the head. On the other
hand, if the phone is mounted
against the waist or other part
of the body during use, then
that part of the body will absorb
more RF energy. Wireless
phones marketed in the U.S.
are required to meet safety
requirements regardless of
whether they are used against
the head or against the body.
Either configuration should
result in compliance with the
safety limit.
Do wireless phone
accessories that claim to
shield the head from RF
radiation work?
Since there are no known risks
from exposure to RF emissions
from wireless phones, there is
no reason to believe that
accessories that claim to shield
>> Health and safety information
the head from those emissions
reduce risks. Some products
that claim to shield the user
from RF absorption use special
phone cases, while others
involve nothing more than a
metallic accessory attached to
the phone. Studies have shown
that these products generally
do not work as advertised.
Unlike "hand-free" kits, these
so-called "shields" may
interfere with proper operation
of the phone. The phone may
be forced to boost its power to
compensate, leading to an
increase in RF absorption. In
February 2002, the Federal
trade Commission (FTC)
charged two companies that
sold devices that claimed to
protect wireless phone users
from radiation with making
false and unsubstantiated
claims. According to FTC, these
defendants lacked a reasonable
basis to substantiate their
claim.
What about wireless phone
interference with medical
equipment?
Radio frequency energy (RF)
from wireless phones can
interact with some electronic
devices. For this reason, FDA
helped develop a detailed test
method to measure
electromagnetic interference
(EMI) of implanted cardiac
pacemakers and defibrillators
