A:Answer Not to worry. Bluetooth is very low power so there is even less radiation than from a cordless phone. Typically, a cell phone has its antenna in a place that's far enough away from your head so there are no serious issues with RF radiation. You need at least one bandwidth from the antenna. Cell sites are much more numerous than they used to be and there is more likely one close to your proximity, unless you are in a very rural area, so your cell phone will need less power to interact with the site. But, it is a good idea to use a headset or ear piece if you are going to be talking for more than a few minutes. Hope this helps.
