The "old" IPS curriculum for junior high students has a good radioactivity lab using low energy sources and polaroid film. I haven't used this material for a few years but I still see it available from several of the educational equipment suppliers such as Hubbard. Students simply put 6 small sample boxes (A-F) on a piece of the film and let it set for 2 to 4 days. Items such as keys or coins could be placed between the box and film to create shadow pictures. (only 3 of the 6 samples were radioactive) Good luck! Bob Carlisle, Physics, Boulder High, Boulder, Colorado
