Scanners, X-rays, and the like scare me quite heavily enough already. I had to get a mouth x-ray semi-recently, and I think I asked the radiologist if it was safe about ten times before I went ahead with it.
Who ever in the hell was their Physicist was needs to be fired because that should have been caught way before then. On average you're getting a years worth of radiation for a head CT and 2 and a half years worth of background radiation for an abdominal study in the course of 10 seconds to 15 minutes and that's for a normal dosage.
@yeti: I have a spectrum analyser for 2.4GHz radio bands and I checked out some BT gear on it... Wi-fi is pretty weak compared to a cel phone, but compared to Wi-fi, Bluetooth barely shows up as a smattering of background noise.
So I'd wondered the same, but looking at it, BT is really negligible. You will literally get more radiation in the same frequency band by standing in the same room as a properly working microwave oven while using it.
The incidence of cancer in our world is WAY up over the historic rate. And cancer is virtually unknown in undeveloped areas of the planet. Coincidence?
@Bandit: I think you have to account for differences in life spans and detection rates if you want to compare the "developed" world to other areas or historical rates. If you don't have CT scans, MRIs, constant mammograms, colonoscopies, and prostate exams, you aren't going to realize/record that what killed someone was unchecked cancer. And, if you're dying because of bad water, bad nutrition, constant warfare, etc, you're less likely to live long enough to get cancer. For all we know, "old age deaths" from times before x-rays, proper autopsies, and the like could actually be cancer deaths.
The SAR limit is in the US is 1.6 W/kg averaged over 1g of tissue. Everywhere else in the world it is 2.0 W/kg averaged over 10g of tissue. The US has the most strict standard in the world.
I don't understand the units of measurement. Watts/Kilogram. Who gives a shit how much the phone weighs. The radiation is the only thing you care about.
Since I'm married I am developing some "man cans", however I would personally rather have a tumor on my breast than on my brain. Also, did it state it was a constant radiation, or was it while the device is being used? I could see smartphones giving off more than others with wifi/3G/GPS and the like being accessed more frequently and also while calls aren't being made.
Then again, if your friends can talk on their phone while it's in their bra... bravo.
My old Treo 650 always got bottom of the charts on these lists. It could make a speakerphone GSM-chirp at 10 feet. But my Cuato sure loved its solid reception.
@FriarNurgle: As someone using Verizon and with a brain tumor I can hear you perfectly. That said, we are all carrying around mini microwave ovens in our pockets, and whether your device is listed at the top or the bottom of the list the risk is likely similar.
So you're saying we should all walk around with a 2.4Ghz radio stuck in our ears? Sounds like a worse idea than occasionally having a phone up to our head every now and then.
@Barry99705: That bluetooth headset only needs to transmit a signal about a meter. The cellphone needs to send a signal about a kilometer. The power difference between the two is huge.
@Barry99705: 10mW at a frequency that doesn't penetrate into skin well vs. 2W at lower frequencies with better tissue absorption... I know which I'd rather take.
