Reducing Exposure: Hands-Free Kits and Other
Accessories
Steps to Reduce Exposure to Radio Frequency Energy
If there is a risk from being exposed to radio frequency
energy (RF) from cell phones - and at this point we do
not know that there is - it is probably very small. But, if
you are concerned about avoiding even potential risks,
you can take a few simple steps to minimize your RF
exposure.
䢇
Reduce the amount of time spent using your cell
phone;
䢇
Use speaker mode or a headset to place more
distance between your head and the cell phone.
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.
