High School Health Physics

["Joel I. Cehn" <jcehn@worldnet.att.net>]

Does anyone have instructions for simple source & geiger counter
experiments?  The HPS is distributing old Civil Defense GM's to high school
science teachers.  They can detect a latern mantle quite well.  We'd like
to include a sheet on experiments, resources, etc.
