Here's a good site: http://trshare.triumf.ca/~safety/EHS/rpt/rpt_7/node16.html.Yes, I realize that it's kinda late now, but I'm sure you're smart enough to already know! :)

Alpha particles are the weakest form of radiation....Beta is the second, can be stopped by a wall of concrete. Gamma rays are the strongest-prolly only stop it by 6 feet of lead of something.
