No need for theories when sadly there is real-world data:

Personal Chernobyl Of Analtoli Bugorski
How the hell is that perfectly well!? Sounds like something out of a Monty Python sketch ... oh just some small seizures, but he's fine really. It's perfectly safe to stick your head in a proton beam kids. Perfectly safe.
Really interesting though, I was under the impression the beams needed a very strong magnetic field to remain stable. How come he was able to stick his head in one?
Which is pretty good, since the initial medical reaction was to watch him die.
