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
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.
