avoiding even potential risks, you can take a few simple steps to minimizeyour exposure to radio frequency energy (RF). Since time is a key factorin how much exposure a person receives, reducing the amount of timespent using a wireless phone will reduce RF exposure.z “If you must conduct extended conversations by wireless phoneevery day, you could place more distance between your body andthe source of the RF, since the exposure level drops offdramatically with distance. For example, you could use a headsetand carry the wireless phone away from your body or use awireless phone connected to a remote antenna.Again, the scientific data do not demonstrate that wireless phones areharmful. But if you are concerned about the RF exposure from theseproducts, you can use measures like those described above to reduceyour RF exposure from wireless phone use.What about children using wireless phones?The scientific evidence does not show a danger to users of wirelessphones, including children and teenagers. If you want to take steps tolower exposure to radio frequency energy (RF), the measures describedabove would apply to children and teenagers using wireless phones.Reducing the time of wireless phone use and increasing the distancebetween the user and the RF source will reduce RF exposure.Some groups sponsored by other national governments have advised thatchildren be discouraged from using wireless phones at all. For example,the government in the United Kingdom distributed leaflets containing sucha recommendation in December 2000. They noted that no evidence existsthat using a wireless phone causes brain tumors or other ill effects. Theirrecommendation to limit wireless phone use by children was strictlyprecautionary; it was not based on scientific evidence that any healthhazard exists.Do hands-free kits for wireless phones reduce risks from exposureto RF emissions?Since there are no known risks from exposure to RF emissions fromwireless phones, there is no reason to believe that hands-free kits reducerisks. Hands-free kits can be used with wireless phones for convenienceand comfort. These systems reduce the absorption of RF energy in thehead because the phone, which is the source of the RF emissions, will notbe placed against the head. On the other hand, if the phone is mountedagainst the waist or other part of the body during use, then that part ofthe body will absorb more RF energy. Wireless phones marketed in theU.S. are required to meet safety requirements regardless of whether theyare used against the head or against the body. Either configuration shouldresult in compliance with the safety limit.Do wireless phone accessories that claim to shield the head fromRF radiation work?Since there are no known risks from exposure to RF emissions from
