Welcome to the forum although none of us wanted to come here. I am not an expert on radiation as I chose surgery. Look for pcdave's thread on proton. He has done a great job on explaining how it works and the effects he had.
Look at the second line from the top of the page for bluebirds index. That will guide you around this site.
Good luck and please stay with us...
