Simple, the blast radius of anything radio related is much, much higher. And if you mess around with transmitters so that they interfere with air or maritime bands or with police/firefighter/EMS comms, it might be the one hole in the swiss cheese too much that leads to a fatal disaster.

Unfortunately, it is at the same time very easy to make innocent mistakes that lead to such kinds of emissions. Say, forget (or mess up) the input filter of a PA, and at the same time mess up the output filter... and whoops, now you're blasting harmonics all over the place.
