Bluetooth Headsets are safe, but the bluetooth transmitter in mobile phone can be dangerous

Though the Bluetooth headset emit very very weak radiations, the signal transmission strength from the phone itself is quite high, as bluetooth headset users frequently keep their phone in a pocket or clipped to the belt.

PRLog - Feb. 16, 2011 - The radio frequency signals emitted from the bluetooth headset are weaker than class 2 power category, operating at peak transmission power of 1 mW in a range of less than 10 meters, but the bluetooth transmitting device from the mobile phone emits radiations at transmission power of around 2.5 mW having a range of upto 30 meters. Though the Bluetooth headset emit very very weak radiations, the  signal transmission strength from the phone itself is quite high, as bluetooth headset users frequently keep their phone in a pocket or clipped to the belt, a position that leads to radiation exposure of internal organs. As stated on the FCC website, “if the phone is mounted against the waist or other part of the body during ' then that part of the body will absorb RF energy” (FCC 2008), but the health effects of this exposure have not yet been assessed. Thus the bluetooth headset is not dangerous to health but the bluetooth signal transmitting device in the mobile phone can bad, so it is strongly advised to use Waveban Cell phone radiation shield alongwith the mobile phone to protect yourself from the bluetooth radiations emitted from the mobile device if bluetooth headset is being used.

To know further more about the bluetooth

Bluetooth transmitters operate at frequency around 2.4 GHz. Bluetooth devices are assigned to one of three power classes: 1, 2 and 3. Class 2 transmitters – most commonly found in mobile devices – have a range of 30 feet (10 meters) and operate at 2.5 mW peak transmission power; class 3 devices are weaker than class 2, operating at peak transmission power of 1 mW in a range of less than 10 meters. Class 1 transmitters are the most powerful, with a range of 300 feet and peak transmission power of 100 mW. Class 1 Bluetooth devices can cause exposure to radiation similar to that emitted by a cell phone if they are operated in the immediate vicinity of the body.

While the radiations emitted from Bluetooth headset are within the specified SAR level, the transmission strength from the phone is quite high. Bluetooth headset users frequently keep their phone in a pocket or clipped to the belt, a position that leads to radiation exposure of internal organs. As stated on the FCC website, “if the phone is mounted against the waist or other part of the body during use, then that part of the body will absorb RF energy” (FCC 2008). While the health effects of this exposure have not yet been assessed, the Swiss FOPH recommended that “cell phones should not be carried in a front trouser pocket when making calls”

Wired earphones are absolutely safe because it neither emit electromagnetic radiation in microwave range nor does it conduct such radiations, but still Bluetooth is more comfortable to use and hard to avoid , thus for protection against the bluetooth radiations emitted from the cell phones transmitter, one should always keep Waveban Cell phone radiation shield behind the cellphone to block the emitted radiation from being incident on body surface.
