![]() It gets even worse if your phone is placed anywhere against your body while you are using Bluetooth (or any headset), such as in your pocket. Therefore, the proximity combined with the more chronic exposure levels, as people tend to use their headsets considerably more often than holding the phone to their head (especially when listening to music), and the dangers of radiation exposure using wireless headsets most likely outweigh the dangers of using your cell phone. Joel Moskowitz says that in reality, due to the much greater proximity of the inside of the head, Bluetooth can affect the head specifically at one-third to one-half the level of a cell phone! It’s not as safe as we were led to believe. The telecommunications industry claims that the body absorbs only a fraction of the radiation from Bluetooth headsets compared to what a cell phone emits, but Dr. This chronic use, and the location of the signal receptors being as close as physically possible to the inner ear and the brain, is problematic. They are more likely to use it daily, sometimes for long periods of time. No one buys a helmet to use only occasionally or for short periods of time. This is exactly how Bluetooth headsets are used. However, weak electromagnetic fields have been shown to be detrimental to health, especially when exposure is of long duration and constant, and in close proximity to a vital organ. The industry claims that the radiation power of Bluetooth is too low to be harmful to health. Many people will experience an obvious thermal effect, and it’s not uncommon to have a headache on the side of the head where the phone is held, which disappears shortly after moving the phone away – or, more tellingly, the headache changes sides when you move the phone to the other side of the head! Not only are the thermal effects not even close to the most dangerous aspect of wireless radiation, but many independent researchers believe that the SAR rate is still set far too high to protect health! Many people can tangibly feel the thermal effect of their mobile phone when they talk with their phone next to their head. This standard is called SAR (Specific Absorption Rate). This means that the device heats up the nearby tissue a lot. As a result, industry safety standards focus entirely on keeping their devices below a certain level of heat absorption effect on the body that someone declared to be safe about 20 years ago. There is a widespread assumption by the telecommunications industry and researchers that since wireless technology, including Bluetooth, is considered non-thermal and non-ionizing, its radiation is harmless. Class 1 devices operate at 100 mW, which is 40 times more powerful than previously popular headsets! However, be aware that some of the newest headsets on the market, such as Apple AirPods and Beats headphones, are sold as Bluetooth Class 1, with a much more powerful 150-meter transmission range. ![]() Most Bluetooth wireless headsets are considered Bluetooth Class 2 devices, with an output power of 2.5 mW and a range of 10 to 20 meters. This is a higher frequency than the spectrum in which cell phones operate. Bluetooth headsets use short-range signals in the 2.4 Ghz band, the same spectrum as WiFi and microwave ovens. Bluetooth technology works by emitting wireless microwave radiation from a transmitter in the base device to a receiver right next to the headset or earphones in your ears.
