Reducing Exposure: Hands-Free Kits and Other
Accessories
Steps to Reduce Exposure to Radiofrequency Energy
If there is a risk from being exposed to radiofrequency 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.
Reduce the amount of time spent using your cell phone;
•
Use speaker mode or a headset to place more distance between your
•
head and the cell phone.
Hands-Free Kits
Hand-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 since 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.
Since 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
Since 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 "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.
