> What ever harm it might be causing, is below the detection threshold, and thus meaningful risk tolerance of everyday life.

The sensitivity of an instrument to detect harm has no relationship to whether there is some ground truth harm. In many cases, like smoking cigarettes or getting hit on the head repeatedly, harm is incremental and compounding---a single event may not be detectable, but it is almost certainly still harmful.

Everything is harmful, from sunlight to food to driving. At issue is cost benefit.
