obtaining input from experts in government, industry and academic organizations.
CTIA–funded research is conducted through contracts to independent investigators. The
initial research will include both laboratory studies and studies of wireless phone users.
The CRADA will also include a broad assessment of additional research needs in the
context of the latest research developments around the world.
What steps can I take to reduce my exposure to radio frequency energy
from my wireless phone?
Again,thescienticdataavailabledoesnotconrmthatwirelessphonesareharmful.But
if you are concerned about the RF exposure from these products, you can use measures
like those described above to reduce your RF exposure from wireless phone use.
Do hands–free kits for wireless phones reduce risks from exposure to RF
emissions?
SincetherearenoknownrisksfromexposuretoRFemissionsfromwirelessphones,
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
bodywillabsorbmoreRFenergy.WirelessphonesmarketedintheU.S.arerequired

Do wireless phone accessories that claim to shield the head from RF
radiation work?
SincetherearenoknownrisksfromexposuretoRFemissionsfromwirelessphones,
there is no reason to believe that accessories that claim to shield the head from those
emissionsreducerisks.SomeproductsthatclaimtoshieldtheuserfromRFabsorption
use special phone cases, while others involve nothing more than a metallic accessory
attachedtothephone.Studieshaveshownthattheseproductsgenerallydonotworkas
advertised.Unlike“hand–free”kits,theseso–called“shields”mayinterferewithproper
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
