If I am remembering my O Level Physics correctly, Alpha particles can only travel a few centimetres before they are absorbed by the air. So they wouldn't be a very effective probe.
Not sure what the feedback mechanism back to Johnny's eyes would be either.
Basically it doesn't pay to start looking into these things too much. So long as the story is consistent with its own established rules, then I can go with that.
WRT cameras in the helmet, well they have never featured in the comic, so they don't exist in that. If a TV or film adaptation wants to go with that, then fine.
