Question

What would happen if you accelerated a proton incredibly fast through a person's body?

Answer 1

Well, an accelerating charge emits radiation and the electric field intensifies, but one proton is so small that it would probably go straight through your body and do minimal damage.

Answer 2

I think in fact that the proton it will pass the person´s body and this person felt something like a sting, and this would hurt the person.
