Hands-Free Kits
Hands-free kits may include audio or Bluetooth
®
headsets and
various types of body-worn accessories such as belt-clips and
holsters. Combinations of these can be used to reduce RF energy
absorption from cell phones.
Headsets can substantially reduce exposure because the phone is
held away from the head in the user's hand or in approved
body-worn accessories. Cell phones marketed in the U.S. are
required to meet RF exposure compliance requirements when used
against the head and against the body.
Because there are no known risks from exposure to RF emissions
from cell phones, there is no reason to believe that hands-free kits
reduce risks. Hands-free kits can be used for convenience and
comfort. They are also required by law in many states if you want to
use your phone while driving.
Cell Phone Accessories that Claim to Shield the Head from RF
Radiation
Because there are no known risks from exposure to RF emissions
from cell phones, there is no reason to believe that accessories
which claim to shield 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 “hands-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.
