Page 18: Consumer Update On Mobile Phones
The U.S. Food and Drug Administration’s Center for Devices and Radiological Health Consumer Update on Mobile Phones FDA has been receiving inquiries about the safety of mobile phones, including cellular phones and PCS phones. The following summarizes what is known--and what remains unknown--about whether these products can pose a hazard to health, and what can be done to minimize any potential risk.
Page 19 How much evidence is there that hand-held mobile phones might be harmful? Briefly, there is not enough evidence to know for sure, either way; how- ever, research efforts are on-going. The existing scientific evidence is conflicting and many of the studies that have been done to date have suffered from flaws in their research meth- ods.
Page 20 FDA is currently working with government, industry, and academic groups to ensure the proper follow-up to these industry-funded research findings. Collaboration with the Cellular Telecommunications Industry Association (CTIA) in particular is expected to lead to FDA providing research recommendations and scientific oversight of new CTIA-funded research based on such recommendations.
Page 21 called a case-control study. The current case-control study of brain cancers by the National Cancer Institute, as well as the follow-up research to be sponsored by industry, will begin to generate this type of information. What is FDA’s role concerning the safety of mobile phones? Under the law, FDA does not review the safety of radiation-emitting con- sumer products such as mobile phones before marketing, as it does with...
Page 22 In the absence of conclusive information about any possible risk, what can concerned individuals do? 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 people are concerned about avoiding even potential risks, there are simple steps they can take to do so.
Page 23: Care And Maintenance
• Do not connect incompatible products. The use of third party equipment or accessories not made or authorized by Mitsubishi Wireless Communications Inc. may be a safety risk. • Do not remove the labels. The numbers on it are important for service and other related purposes.
