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.
