In school, we used to learn about the RF service technicians returning with stories of dead birds and other such phantasmagoria in and around the sweet spots of the feedhorn, antenna, transmission line, transmitter or other such sensitive areas of high power microwave operations.

Professor also admonished us that such technicians must always be infinitely certain that the transmitter is not operational at the time of service.

It's a good thing your professor is not a tower technician. No self respecting technician climbs up a tower without knowing his potential exposure.

There is a reason both the US FCC and EU ICNIRP have guidelines for human exposure, and if you are a tower technician you wear a personal RF densitometer to ensure you are not exposed above these levels.

"Electromagnetic field densitometers, as used in the cellular phone industry, are referred as "personal RF safety monitors", personal protection monitors (PPM) or RF exposimeters.[1] They form part of the personal protective equipment worn by a person working in areas exposed to radio spectrum radiation."

And even with a densitometer, when working on high-powered live equipment, you also wear a protective suit:

I hope you forward this information to your professor. Industrial RF radiation is not something you want to play around with.

I saw a video recently where a guy took a densitometer to a street with 5g in my country, and lets just say that there was plenty of sweet spots where it was well over 500uw/m2. Im no expert or anything, but seems like allowing 4 different vendors to put up 5g infrastructure all over the place might not be such a great idea.

hmm your comment makes it sound as if I had said that my professor recommended reckless abandon such that we should climb the tower in swimwear during a heavy rain after cranking the tranmitter to maximum?

I believe these "sweet spots" are technically referred to as "modes". Think of them as "balls" of RF located in a specific area.
