    Are Bluetooth devices really safer than using a cell phone?

    From Cindy Sage on the supposed safety of Bluetooth devices:

    People should realize that Bluetooth devices that fit in or around the ear typically radiate at 0.23 watts per kilogram (W/Kg). Go into any AT&T wireless store and ask for the SAR on Bluetooth devices. Or check any SAR values website that shows cell phone SAR levels, and you’ll find the Bluetooth devices are actually worse than some of the low-SAR cell phones.

    This level of 0.23 W/Kg is ten to 100 times higher than the RF exposure levels shown to make the blood-brain barrier pathologically leaky, allowing toxins and toxic molecules to cross the BBB. This is reported by Salford, Persson, NIttby and Schirmacher among others – to cause neuron death at 0.012 to 0.002 W/Kg.

    Multiple studies have reported that as short as a single, two-hour exposure to cell phone radiation will result in pathological leakage of the blood-brain barrier. The effect occurs immediately, and is still seen at 14 days and at 50 days post-exposure at only 0.012 W/Kg to 0.002 W/Kg. The lowest exposure SARs are worse than the higher SAR exposures (Nittby et al, 2009). These studies show neuron death (brain cells) at SARs of only 0.012 W/Kg. Bluetooth devices are worn for hours at a time, in some cases – all day long. So, it is reasonable to conclude that a device which radiates at a higher intensity than some cell phones that are still risky in terms of SAR, worn for more hours than a cell phone is typically used – would not be a good idea to promote.
