It is the licensee's responsibility to ensure that no one is exposed to high levels of RF according to the FCC exposure standards. As I understand it, the rigger cannot excuse you from that liability. If he adamantly climbs your tower after you told him not to, and you know he's climbing, it is your responsibility to keep him from being exposed. By turning the system off if necessary.

We say over here: "the devil is in the details". Same so with this item. Going to wavelenghts in the direction
of microwaves is never good but radar in ww II used often 27 Mc. AM + FM power radio people go unschaved
but TV is an entirely different story. The trick is the modulation. Is there square involved like digital and
sync modulation which is also square. That's also the answer on speedradar, cellphones etc.
I had two collegues (age 30's) working somewhere before a televisionwall (repaircenter) They both got a braintumor !
How come you ask, no rf. Well the magnetic deflectionfields are strong enough and sharp edged that we can wait for
an accident to happen. Same for British police who got a 'digital network' portophones. And yes they fall like leaves
with braincancers. So you are warned now.

One has to wonder if these GSM phones we stick right up against our heads at near-microwave frequencies might not be such a great idea really. The interesting trend is that so many have internal antennas the are even closer to the scull.....
I’ll make this comment regarding cell phones. The only kind I ever had was a permanent installation in a car with the antenna in the rear window, how ever . . .
I ended up with a Pituitary brain tumor that was removed by two operations and was benign (thankfully). I’ve been in broadcast engineering for 40 years in everything from 250 watts to 50 kilowatts AM and 1 to dual 25 kilowatt FM’s.
I spent too much time working at the base of AM towers and adjacent to high power transmitters. I do not know the cause of my tumor, but I have always suspected something.
I do know other engineers who worked at the same sites as I have having various types of cancerous tumors.

I believe that the hard medical research, as compared to Internet hearsay, shows that the most damage is caused by higher frequencies due to tissue and cell heating. Tissue heating with VHF and UHF, and getting to the cell level at 800 mHz and above.
This was a study that I read after an employees was convinced that her medical problem was related to the transmitter in the building, (although measurements at ground level showed nothing more than what any of us would experience in our own homes). That said, I worry more about my cellphone than AM or HF.

My early experience with an old Collins 1952 series AM invovled getting inside the cavity while it was operational. "What are all those pices of wood on this shelf?" And the 2nd engineer of the place (on in 1921) said "they bypass the interlocks."
Most old engineers lived despite the lf rf.
My read on the microwave problems involves people who sat in front of the dish to stay warm then no one told them of a power increase and they died.
Silliman often used a screwdriver to arc an antenna and he's still alive. (Won't say where). Class A.
Most of us still have the pcb oil in us. Bounty was the quicker picker upper before we knew any better.
Stillthink cell phones are responsible for gen X though.
