Again, thescientific data do not demonstrate that wireless phones are harmful. But if you areconcerned about the RF exposure from these products, you can use measures likethose described above to reduce your RF exposure from wireless phone use.10. 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 exposureto radiofrequency energy (RF), the measures described above would apply tochildren and teenagers using wireless phones. Reducing the time of wirelessphone use and increasing the distance between the user and the RF source willreduce RF exposure. Some groups sponsored by other national governmentshave advised that children be discouraged from using wireless phones atall. For example, the government in the United Kingdom distributed leafletscontaining such a recommendation in December 2000. They noted that noevidence exists that using a wireless phone causes brain tumors or other illeffects. Their recommendation to limit wireless phone use by children was strictlyprecautionary; it was not based on scientific evidence that any health hazardexists.11. What about wireless phone interference with medical equipment?Radiofrequency energy (RF) from wireless phones can interact with someelectronic devices. For this reason, FDA helped develop a detailed test method tomeasure electromagnetic interference (EMI) of implanted cardiac pacemakersand defibrillators from wireless telephones.This test method is now part of a standard sponsored by the Association forthe Advancement of Medical instrumentation (AAMI). The final draft, a jointeffort by FDA, medical device manufacturers, and many other groups, wascompleted in late 2000. This standard will allow manufacturers to ensure thatcardiac pacemakers and defibrillators are safe from wireless phone EMI. FDAhas tested hearing aids for interference from handheld wireless phones andhelped develop a voluntary standard sponsored by the Institute of Electrical andElectronic Engineers (IEEE). This standard specifies test methods and performancerequirements for hearing aids and wireless phones so that that no interferenceoccurs when a person uses a “compatible” phone and a “compatible” hearing aidat the same time. This standard was approved by the IEEE in 2000. FDA continuesto monitor the use of wireless phones for possible interactions with other medicaldevices. Should harmful interference be found to occur, FDA will conduct testingto assess the interference and work to resolve the problem.12.
