153Some groups sponsored by other national governmentshave advised that children be discouraged from usingwireless phones at all. For example, the government inthe United Kingdom distributed leaflets containing sucha recommendation in December 2000. They noted that noevidence exists that using a wireless phone causes braintumors or other ill effects. Their recommendation to limitwireless phone use by children was strictlyprecautionary; it was not based on scientific evidencethat any health hazard exists.7. Do hands-free kits for wireless phones reduce risksfrom exposure to RF emissions?Since there are no known risks from exposure to RFemissions from wireless phones, there is no reason tobelieve that hands-free kits reduce risks. Hands-free kitscan be used with wireless phones for convenience andcomfort. These systems reduce the absorption of RFenergy in the head because the phone, which is thesource of the RF emissions, will not be placed againstthe head. On the other hand, if the phone is mountedagainst 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 tomeet safety requirements regardless of whether they areused against the head or against the body. Eitherconfiguration should result in compliance with the safetylimit.8. Do wireless phone accessories that claim to shield thehead from RF radiation work?152If there is a risk from these products—and at this pointwe do not know that there is—it is probably very small.But if you are concerned about avoiding even potentialrisks, you can take a few simple steps to minimize yourexposure to radiofrequency energy (RF). Since time is akey factor in how much exposure a person receives,reducing the amount of time spent using a wirelessphone will reduce RF exposure.If you must conduct extended conversations by wirelessphone every day, you could place more distance betweenyour body and the source of the RF, since the exposurelevel drops off dramatically with distance. For example,you could use a headset and carry the wireless phoneaway from your body or use a wireless phone connectedto a remote antennaAgain, the scientific data do not demonstrate thatwireless phones are harmful. But if you are concernedabout the RF exposure from these products, you can usemeasures like those described above to reduce your RFexposure from wireless phone use.6. What about children using wireless phones?The scientific evidence does not show a danger to usersof wireless phones, including children and teenagers. Ifyou want to take steps to lower exposure toradiofrequency energy (RF), the measures describedabove would apply to children and teenagers usingwireless phones. Reducing the time of wireless phoneuse and increasing the distance between the user andthe RF source will reduce RF exposure.AAppppeennddiixx AAppppeennddiixx
