Bob,
I am not aware of anyone that is using a broadcast station as a Rife machine, but if they are they should certainly have the courtesy to shut off that 100kw transmitter before allowing anyone on the premises to climb the tower.
Your are mixing up occupational safety regulations applicable to the broadcast industry with medical applications, which are hopefully intentional. We all try very diligently to stay out of the broadcast field, either by intention or accident. In any case the equipment being discussed is in a historical context, though we all really wish one or more of these had been preserved.
If someday somebody can recreate the true Rife effect, I am sure dilligent effort will be made to find a way to build it so it is effective while not making the FCC unhappy. Until then the problem generally remains in the realm of the hypothetical.
