Why are you not worried about the unknown unknowns in literally any other area? Like, using microwave ovens, having TV broadcast signals, or wearing silk? Personally I'm reasonably confident that any significant adverse health effect would have been found by experiments by now, so Bayesian reasoning tells me any unknowns that are still unknown are probably negligible.
