To do the math, I believe the current suggested radiation level maximums for continuous exposure at in the range of 1 milli-watt per cubic centimeter of absorbed radiation. With TPO power levels under a watt, well under a watt in most cases, one would almost have to stick the antenna in your ear or mouth to exceed this by a sufficient margin as to be cause for a health concern, particularly given the relatively short period one could tolerate it, and then I'd be more worried about the cleanliness of the antenna if I was to use it for a toothpick than about any radiation concerns. Using your cellphone is a far larger risk in general. >From a foot away, its 100% safe, from 3 floors away you'll die of old age like I intend to.
