Radon in mines was recognized as a hazard long ago. Exposure limits were set in the late 60's - early 70's by state and federal regulators.
The whole problem of how to regulate substances/energies that are ubiquitous is vexing everyone.

This was a right on answer. One reason for my question is that I spoke with
a regulator some time ago and he was clearly against any classification like
"occupational exposure". (I am not saying that it should be regulated - it
was more a question of the logic - and that the general public probably
don't know much about it - I agree with your next comment below). Radon in
mines is not a licensed source I suppose? (or?)
