My little Cs-137 check source is getting a bit old and is probably about one 
half-life down in activity.  Any suggestions for a relatively cheap source 
of button check sources in this over-regulated world?  You used to be able 
to get em cheap from the school science supply houses, but they are 
apparently afraid of radiation these days.
