Ok. That answers the main question I had. However, the question was like 10pages long
The main reason I asked the question was because of the movie 'Fortress'.
Those who've seen it remember the sentinel gun of the prison that shot a burst of neutrons at one of the prisoners leaving a hole in his stomach.
I was wondering how could the atoms evaporate from the human being just by being hit by neutrons (no charge, and that according to my wife) means the atoms should not react to the particles.
