Study Finds That Cell Phone Radiation Temporarily Affects the Brain

Cell Phone Use Affects Brain Temporarily, Say ResearchersA new study released Wednesday in the Journal of the American Medical Association revealed that 50 minutes of continuous cell phone use causes temporary changes in the brain. That period of cell phone use was associated with increased brain metabolism of sugar in the region closest to the phone antenna. However, researchers cautioned that it was too early to determine whether these change are harmful.

"The dramatic worldwide increase in use of cellular telephones has prompted concerns regarding potential harmful effects of exposure to radio frequency-modulated electromagnetic fields (RF-EMFs)," and the potential carcinogenic effects from those emissions, the study authors note. Yet studies trying to find a link between "cell phone use and prevalence of brain tumors have been inconsistent (some, but not all, studies showed increased risk), and the issue remains unresolved," they add.

Similarly, studies to investigate the effects of RF-EMF exposure from cell phones have yielded variable results. Dr. Nora Volkow of the National Institutes of Health and her colleagues tried to evaluate if acute cell phone exposure affects brain glucose metabolism, a marker of brain activity.

Researchers scanned the brains of 47 participants using Samsung model SCH-U310 cell phones both during phone use and with the phones deactivated. They found that whole-brain metabolism did not differ when the phones were on, but there were significant regional effects. Metabolism in the brain region closest to the antenna (orbitofrontal cortex and temporal pole) was significantly higher (approximately 7%) when the cell phones were on than when they were off.

"These results provide evidence that the human brain is sensitive to the effects of RF-EMFs from acute cell phone exposures" and "that acute cell phone exposure affects brain metabolic activity," the authors write. But the researchers are unclear how RF-EMFs could affect brain glucose metabolism.

Possible Health Consequences Are Still Unknown


The researchers also caution it's too early to draw any conclusions. "[T]hese results provide no information as to their relevance regarding potential carcinogenic effects (or lack of such effects) from chronic cell phone use." They conclude, "Further studies are needed to assess if these effects could have potential long-term harmful consequences."

An accompanying editorial in JAMA notes that even though the health consequences are unknown, the results "add to the concern about possible acute and long-term health effects" and raise several question such as how an increase in metabolism affects brain function and consequently organs, and whether there is possible chronic increased metabolism from regular use.

Other experts are even more cautious about drawing conclusions, pointing to years of inconclusive and conflicting results from studies of cell phones. An estimated $100 million or more has been spent so far around the world on research into possible health risks from using mobile phones with no solid findings. The largest study on 420,000 mobile phone users in Denmark, found no link between phone use and cancer.

Worldwide mobile device sales to end users totaled 1.6 billion units in 2010, a 31.8% increase from 2009, according to Gartner Research. Another estimate puts shipments of mobile phones in 2010 at nearly 1.3 billion, which is worth $172.2 billion -- a number that's expected to double by 2015. By June 2010, the CTIA estimated there were 292.8 million active mobile phones in the U.S., and the estimates range between 4 billion and 6 billion phones worldwide. Whatever the true number is, it's growing rapidly.

I don't need scientific confirmation of a threat of cancer to want to take precautions with cell phones. I am not a doctor or medical professional. However, I think some common sense is called for here...there's been a WHO report released which condemns the use of cell phones as probably carcinogenic..I am most concerned with children talking on a cell phone. Their brains absorb more pulsed radio frequency radiation from cell phones. The radiation penetrates half way through the brain of a 10 year old talking on a cell phone and 3/4 of the way through the brain of a 5-year old..Good post. Check my blog post for updated new research reviews on cell phone hazards..there is also a new leap into a military stealth technology that guarantees with proof to block 85% and more..http://to-know.site88.net/ ..

Possible health consequences still unknown, yet EMF pollution spreading and multiplying freely around us as if everything is just fine and safe. It's not about what can I personally do to adjust my living habits to reduce EMF radiation exposure, it's about EMF pollution we have absolutely no insight and control over it. Outdoor man made EMF radiation sources were the primary reason why I decided to use EMF protection device ( http://www.emfprotectionstore.com/ ) because it's something I'm exposed to whether I like it or not.

2500 X more Radiation
cell phone are 0.6 watts. Ham Radio also known as amateur radio are 1500 watts !
you tube video [ Antenna Stirs Up Controversy ] identify how ham radio looks like by antenna type ( they looks like monster TV antenna ) , make thing worse, many of ham radio wave is same frequency ( 2.4 GHZ ) as microwave oven or even higher. most powerful microwave oven are rated 1200 watts.

WOULD YOU STICK YOUR HEAD

IN A MICROWAVE OVEN?

EXPERT DISCUSSES CONTROVERSY
OVER CELL PHONE SAFETY.

Today there are an estimated seven hundred million cell phones in the world. In Europe 80% of the population uses them, compared to 50% in the US. The US. market is growing quickly . All this points to one fact: cell phones are BIG business. Even though the health risks from radiation are being reported and the evidence is mounting, the industry giants continue to claim their products are safe.
Shelly Kalnitsky, an authority on cell phone issues wants to ask your listeners three questions.
1. Do you now believe nicotine is non-addictive?
2. Do you now believe that cigarette smoking does not cause lung cancer?
3. Do the words “radiation” and “microwaves” sound like something you want going into your brain?

“The jury is still out on the extent of the long term effects of cell phones” says Kalnitsky “but we are discovering more evidence of cell phone dangers.” He points to an independent reporting site cprnewsbureau.org which documents hundreds of articles , studies and research on cell phone dangers.
He discusses :
• How the industry suppresses negative stories.
• The increased risks cell phones pose to teens and children.
• Why current hands free kits are more dangerous.
• New products that can reduce the risk.
• Safety tips in cell phone usage.

Kalnitsky is an expert on the subject and can add insight on recent scientific findings as well as discuss protection devices such as shields, new hands free radiation free kits and safety tips that can offer a remedy for cell phone users.

Why worry about any of it...? If the losers we placed in office continue to view the working man in the same vain as ''Free Nights And Weekend'' we won't have a reason to have any phones cemented to the side of a head chancing a fried noodle..,When the working class can't afford to pay For them anyway !
But, No..., we have to keep the ''China phones'', whats the hourly rate behind the ''Great Wall'' ? 30 cents a hour...,maybe..! Oh..,and not the silghtest bit of interest in workers heath, safety...Just anything ..., they don't care if it is copyright, patent..They rip off every idea..make it cheap because of a cheap labor and no working conditions. Just..''Build Build Build''...,so we ''Buy..Buy.., Buy''...And sell ourselfs out just as quick as the out of touch losers we placed in office!! How 'bout ..'' Buy American While You Still Have America To Buy In''?....or, Just wait til' Dec 21, 2012...All our problems will be over soon enough....Bring It On'' Bitches!!!! ''

There seems little doubt that extended cell phone use has to have a negative effect on at least some. This is the catch 22 of humanity advancing.

Radiation to Brain?? Yes its a killer. -lol
How lame can you be.
All Radiation, esp to your brain is bad, and deadly.

Wake up people!
Your government is lieing to you!

Another important little health tidbit. Let's put it with the British study on red meat and cancer. Add that to no cooking over charcoal, only one egg a day, no saran wrap in the microwave, don't eat old tuna fish and the thousands of other don't that these clowns come up with and we can just stay in our sterile homes and stare at the walls.
