Are wireless or wired headsets better for reducing cell phone radiation exposures?
The jury is out on whether a wireless or wired headset is better for reducing radiation exposures but either is preferable to a phone held to the ear. The governments of Switzerland, Germany, Israel and Finland, the European Parliament and the city of Toronto all recommend using a headset or an earpiece as a precautionary measure. But expert recommendations differ on the type some recommend wired, some wireless. A wireless headset, such as Bluetooth, uses radiofrequency radiation to communicate with a cell phone. This is the same form of radiation emitted by cell phones. But the signal travels only a short distance from the ear to the phone, so wireless headset emissions are lower than emissions for a cell phone, which transmits to a distant tower. Some wireless headsets emit continuously, even when you’re not on a call. EWG recommends that you take your headset off between calls. Multiple research teams have found that corded headsets also reduce the overall radiation exposure to the
