What's the model of your brain toaster?

Did you ever saw any of these videos about making pop-corn with a mobile phone? Well, they seem to be true. Do you believe them? Try it yourself and you'll see what happens.
Growing concerns about the use of these devices, relayed on recent scientific studies, are disturbing all users around the world. Does your cell phone affects your brain, putting your health in danger? Probably yes. You can read it on the fresh issue of Best Life magazine. They put the finger on all the keys flowing down through these matters.
Did you ever heard about Specific Absorption Rate, commonly known as SAR number? It's another SAR different from the one you are used to, nothing to do with special regions. This is the rate that measures the absorbed radiation by the human body. And some phones are more danger than others, iPhones, for instance, are on the middle range on this. Maybe you believe that for the hours you've already spend on a cell phone probably you wouldn't be here reading this and you don't care much. Perhaps this is not truly scientific confirmed yet but for your own sake you should take a look about it. First rule: don't let your kids use it! Second rule: always use a wired headset (even the Bluetooth devices can be harmful with long time use).

The truth about the cell-phone–cancer link and what it means for you and your kids

When Vini Khurana, PhD, an Australian (and Mayo Clinic–trained) neurosurgeon, announced that the link between cell-phone use and cancer was irrefutable—the result of his analysis of more than 100 studies—it set off alarm bells around the world. Use a cell phone, he said, and you increase your risk of developing a malignant brain tumor by two to four times. Until recently, the majority of research indicated little or no link between cell phones and cancer (the World Health Organization and the American Cancer Society maintain that cell phones pose no threat), but several new long-term studies have cast doubt about their safety. Given that cell phones and PDAs serve as lifelines for so many people—24 percent of 10- and 11-year-olds carry them—it raises urgent questions. To find out what precautions you should take when using your cell phone, we dialed the nation's leading experts.

Do cell phones cause cancer?
Maybe…with extended use. Mobile-phone users are twice as likely to develop malignant, difficult-to-treat brain tumors called gilomas, according to a first-of-its-kind study that analyzed the effects of cell-phone use over 10 years or more and was published last year in the journal Occupational Environmental Medicine. The Bioinitiative Working Group, an international coalition of scientists and public-health experts, recently published a hefty report detailing the link between the nonionizing radiation caused by a cell phone's electromagnetic fields (EMFs) and cancer, DNA damage, Alzheimer's, and other diseases. "The cells in the body react to EMFs in cell phones just like they do to other environmental toxins, including heavy metals and chemicals," says Martin Blank, PhD, a professor in bioelectromagnetics at Columbia University and one of the report's authors. The study found that risk from cell-phone use starts at 260 lifetime hours.

Do cell phones emit radiation only when you are talking?
No. "Cell phones give off radiation any time they're turned on so that they can communicate with base stations," says Lou Bloomfield, PhD, professor of physics at the University of Virginia and author of How Everything Works: Making Physics Out of the Ordinary. "The radiation emitted, however, is stronger and more frequent when you're talking or messaging." Also, the greater distance you are from a base station, the more radiation your phone must emit in order to get a signal, which is why your phone feels hot when you have low reception. That heat you feel is radiation. The Bioinitiative study found that adverse effects to DNA can also occur before the phone heats up. To reduce your exposure, make calls only when you have strong reception, hang up before your phone heats up, and store your phone away from your body when it's not in use.

What is the range of the radiation?
Exposure to radiation from your cell phone drops off slowly for the first three to four inches from your body, and then it falls dramatically, says Bloomfield. To reduce your exposure, invest in a hands-free headset and limit the amount of time you spend talking on the phone. Khurana recommends using the speaker mode and holding the phone about eight inches away from you. Also, limit your use of Bluetooth devices. While it's true that they emit the least amount of radiation (one study found they can operate as low as 0.001 watts per kilogram), even that can add up fast.

Is it risky to carry a cell phone in your pants pocket?
Maybe. One 2006 study found no link to testicular cancer, but other researchers suspect a link to male infertility. Ashok Agarwal, PhD, director of the Center for Reproductive Medicine at the Cleveland Clinic, recently completed a study in which cell phones were set down for one hour in talk mode, next to sperm samples in test tubes. He found that the sperm's motility and viability were significantly reduced, and levels of harmful free radicals increased after exposure. Agarwal suggests storing the phone in your jacket pocket to reduce exposure to cell-phone radiation. Pregnant women need to take precautions too, because a recent study found that cell-phone use while pregnant is linked to behavioral problems in children.

    Mobile phone pop-corn videos are reported to be faked.
    Did you try?

    Thank you for your links.
    If all of these was really true, for the time spent on cell phones, everybody would be dead by now.
