Does blue tooth cause any radiation damages?

Question

Has there been any research on this kind of radiation damages?

Answer 1

There have been many studies into Radio Frequency (RF) absorption into tissue and whether or not it causes damage. Cellphones are the biggest target, because they contain a radio transmitter which you hold on or near your head. The FCC uses a test called SAR (specific absorption rate) to measure radiation absorbtion rates into tissue. The Wiki entry for SAR:

"SAR is a measure of the rate at which radio frequency (RF) energy is absorbed by the body when exposed to radio-frequency electromagnetic field. The most common use is in relation to cellular telephones. In the United States, the Federal Communications Commission (FCC) has adopted limits for safe exposure to RF energy produced by mobile devices and requires that phones sold in the U.S. have a SAR level at or below 1.6 watts per kilogram (W/kg) taken over a volume of 1 gram of tissue. In the EU the corresponding limit is 2 W/kg taken over a volume of 10 grams."

Bluetooth devices, by their very nature, are short-distance radio communication devices, and so will operate at a far lower radio emission level than their cellular cousins. A study by William G. Scanlon of Queen's University in Belfast found that a typical Ericsson Bluetooth radio module generates a SAR of just 0.001 watts per kilogram, which is well within the safe limits.

Answer 2

Bluetooth uses also the microwave frequency spectrum in the range of 2.4 GHz to 2.4835 GHz. The radiated output power of Bluetooth devices is very low in power, so it is assumed that the potential health consequences are lower than other wireless devices. Bluetooth devices can operate continuously or sporadically (on demand), so total exposure to EMF radiation is very variable.

yeah. you're gunna die...
no it doesn't cause radiation damages....
