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!
