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.
Children and Cell Phones
The scientific evidence does not show a danger to any users of cell phones from
RF exposure, including children and teenagers. The steps adults can take to
reduce RF exposure apply to children and teenagers as well.
• Reduce the amount of time spent on the cell phone;
• Use speaker mode or a headset to place more distance between the head
and the cell phone.
