US Government Accountability Office recommends FCC reassess radiation limits for mobile phones
The topic of mobile phone radiation is once again on the burner in Washington D.C. Along with Representative Dennis Kucinich's proposed legislation that would institute labeling requirements and extensive research into the health effects of RF exposure, the US Government Accountability Office has issued a recommendation that the FCC update its current exposure limits and reevaluate current testing methodologies. As is, the FCC's radiation guidelines are based on research that was concluded in 1996, and while the US GAO concedes that this may lead to the adoption of higher SAR limits (in certain usage scenarios), the organization contends that it's time to bring current research and international recommendations into consideration. As potential cause for concern, the US GAO has also identified a failure of current testing methodologies. Put simply, manufacturers are currently required to submit specific absorption rates that reflect usage against both the head and body, however in the case of the body test, this is always done with the assumption of a holster. While a distance of 1.5 to 2.5 centimeters may not seem like much, SAR values increase with proximity, and many who use their mobile phones in their pockets -- say, with a Bluetooth headset -- are at risk of exposing themselves to RF limits that exceed current guidelines. The actual absorption rates are currently unknown. For its part, the FCC has responded to the US GAO and asserts that it has independently arrived at many of the same conclusions, and adds that it has initiated the procedural requirements necessary for the reevaluation of RF safety rules. Those who'd like to learn more can scour the complete recommendation, along with Rep. Kucinich's proposal, at the source links below.
Cellphones are dangerous / not dangerous: Danish study tilts toward the latter
Chalk one up for the chatterboxes. In a study spanning 18 years and more than 350,000 test subjects, researchers in Denmark have found no connection between cellphone usage and brain cancer. The landmark project, carried out by Denmark's Institute of Cancer Epidemiology, was published online last week in the British Medical Journal, and is just the latest in a series of similarly optimistic studies. Of the 358,403 cellphone owners examined, only 356 were found to have a brain tumor, while 856 were diagnosed with cancer of the central nervous system -- percentages that are comparable to those seen among non-mobile users. Even among long-term cellphone owners (13 years or more), incidence rates were not significantly higher than those observed among the general population. Hazel Nunn, head of evidence and health information at Cancer Research UK, described the study as "the strongest evidence yet that using a mobile phone does not seem to increase the risk of cancers of the brain or central nervous system in adults." The study's authors, however, acknowledge some shortcomings in their work, including the exclusion of "corporate subscriptions" -- people who use their mobile devices for work, and who probably use them more heavily than the average consumer. They also recognized the need for longer-term research and for more child-specific studies. You can check out the article in full, at the coverage link below.
Cellphones are dangerous / not dangerous: little tykes under the spotlight
In the rough and tumble debate surrounding the mobile phone's ability to cause cancer, both sides agree that our young ones -- indeed, some of the heaviest users -- could be at an increased risk for cellular-induced tumors. According to a study published in the Journal of the National Cancer Institute, the radio emissions from mobile devices penetrate much deeper into the brains of children, and in the case of little tykes ages five to eight, their noggins will absorb twice the energy of the average adult. This, combined with their developing nervous systems, has brought concern for the welfare of our youngest mobile-savvy citizens, and led to a European study of nearly 1,000 (informed?) participants. Data was gathered over a four-year period, which relied upon self-reporting methods, where youngsters were found to not talk very often, and typically sent text messages instead -- big surprise, right? While long-term risks remain unknown, the researchers conclude that "a large and immediate risk of cellphones causing brain tumors in children can be excluded." In other words: little Suzy won't begin sprouting cancer cells overnight. While you doting parents may find comfort in the latest research, you might consider stopping short of giving the mischievous rascal an unlimited voice plan. After all, gossip still spreads best at the school yard. [Image courtesy Derek Olson (flickr)]
Cellphones are dangerous / not dangerous: Danish chatterbox edition
Concerned that a decade and a half of regular cellphone will have a long-term effect on your health? Hopefully the latest study conducted by members of the World Health Organization (WHO) will put your mind at ease. The examination followed nearly 3 million Danish adults, studying links between phone use and the formation of acoustic neuromas -- non-cancerous, slow-growing brain tumors that form on the main nerve that connects the inner ear to the brain. The study concluded that people who've used a handset for 11-15 years weren't any more likely to develop a tumor than those who don't use cellphones at all, though scientists are unsure that this is a long enough period of time to determine a significant correlation (or lack thereof). Still, this comes as refreshing news two months after the WHO released a study revealing that RF waves coming from phones are "potentially carcinogenic," due to a limited link to glioma and acoustic neuroma. Of course, none of these reports can actually conclude that cellphones cause cancer -- only that the two may be correlated. So, what does this latest study really do? It legitimizes the need to conduct more studies.
Cellphones are dangerous/not dangerous, bee killing edition
Apparently, we should all feel incredibly guilty for simply using our cellphones, as not only are we encouraging the growth of ear tumors within our bodies, but now we're hearing that radiation flying out from our mobiles are demolishing the world's supply of crops. All jesting aside, a controversial report is now claiming that "radiation from mobile phones are interfering with bees' navigation systems, preventing the famously homeloving (and pollinating) species from finding their way back to their hives." The comically-named Colony Collapse Disorder (CCD) is reportedly being seen on a much larger scale in the US and Europe, and elusive "evidence" is purportedly backing these dodgy claims up. Backers of the shocking data are even going so far as to suggest that in the future, our refusal to set aside the cellphone could cause "massive food shortages as the world's harvests fail." Man, this sounds worse than Y2K, for sure.[Via Slashdot]
