Is all that wireless technology really safe?

How safe is all this wireless technology? The folks at website BagSnob asked me this question regarding a new Bluetooth toothbrush sold in Apple store. Their concern was that with all the Bluetooth and wireless technology we use, there might be some harm.  The truth is that while services like wireless and bluetooth are radiofrequency techologies, and thus technically "radiation," the kind of energy they emit has been shown in studies not to be harmful.  A recent study regarding cell phone usage was also somewhat reassuring.
