I think it's a question worth answering simply because there are people out there who fear magnetic fields, be they from power lines, electromagnetic transmitters or otherwise. I've seen the effects of magnetic fields referred to in several posts from people trying to prove that Chinese 5G bats are causing covid.

Some basic research and napkin math to show people they have nothing to fear might be useful, although I'm not sure how far you'd get in a discussion with people that firmly believe in such nonsense.

I'm also kind of curious what the lethal dose of neutrinos would be. I know humanity will be burned to a crisp by an exploding sun before a neutrino overdose would ever become a problem, but if there's a theoretical deadly dose I'd be interested to know it.
