Certification and safety information for the United States and countries using FCC standards

FDA and the Cellular Telecommunications & Internet Association (CTIA) have a formal Cooperative Research and
Development Agreement (CRADA) to do research on wireless phone safety. FDA provides the scientific oversight, obtaining
input from experts in government, industry, and academic organizations. CTIA-funded research is conducted through
contracts to independent investigators. The initial research will include both laboratory studies and studies of wireless phone
users. The CRADA will also include a broad assessment of additional research needs in the context of the latest research
developments around the world.
What steps can I take to reduce my exposure to radiofrequency energy from my wireless phone?
If there is a risk from these products--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 exposure to radiofrequency
energy (RF). Since time is a key factor in how much exposure a person receives, reducing the amount of time spent using a
wireless phone will reduce RF exposure.
If you must conduct extended conversations by wireless phone every day, you could place more distance between your body
and the source of the RF, since the exposure level drops off dramatically with distance. For example, you could use a headset
and carry the wireless phone away from your body or use a wireless phone connected to a remote antenna.
Again, the scientific data
do not demonstrate that wireless phones are harmful. But if you are concerned about the RF
exposure from these products, you can use measures like those described above to reduce your RF exposure from wireless
phone use.
What about children using wireless phones?
The scientific evidence does not show a danger to users of wireless phones, including children and teenagers. If you want to
take steps to lower exposure to radiofrequency energy (RF), the measures described above would apply to children and
teenagers using wireless phones. Reducing the time of wireless phone use and increasing the distance between the user and
the RF source will reduce RF exposure.
Some groups sponsored by other national governments have advised that children be discouraged from using wireless
phones at all.
Do hands-free kits for wireless phones reduce risks from exposure to RF emissions?
Since there are no known risks from exposure to RF emissions from wireless phones, there is no reason to believe that
handsfree kits reduce risks. Hands-free kits can be used with wireless phones for convenience and comfort. These systems
reduce the absorption of RF energy in the head because the phone, which is the source of the RF emissions, will not be placed
against the head. On the other hand, if the phone is mounted against the waist or other part of the body during use, then that
part of the body will absorb more RF energy. Wireless phones marketed in the U.S. are required to meet safety requirements
regardless of whether they are used against the head or against the body. Either configuration should result in compliance
with the safety limit.
