There is a RF safety calculator available at:
I can't personally vouch for the accuracy - perhaps someone else can?
But if it's correct, very few of us have anything to worry about. For
example, I have a 160/80 meter ground mounted vertical which I like to
pump 1500 watts into. According to the calculator, on 80 meters, any
distance farther than 6.15 feet is ok for an "uncontrolled"
environment, and a mere 2.78 feet is ok for a "controlled"
environment. 160 meters is even less.
I also have a TH5Mk2 at 50 feet. With the same 1500 watts, it is ok
on all bands except 10, where I must reduce the power to 1300 watts.
No big deal.
