Is this the Jim Reese of Rancho Seco fame????  If so, mail me back & I'll
add your address to my book.

     The NRC has published guidelines for decay in storage in an 
     Information Notice issued a couple of years ago that should answer all

     your questions.  If I remember correctly, it provides information on 
     the number of half-lives that material must be held to be considered 
     no longer of concern. I don't remember the number right off.  Perhaps 
     a visit to their home page would help or one of the NRC types on here 
     could be of assistance.

Radsafers,
     
At what time does a short lived sealed source cease being 
radioactive material.   Especially if the source has documenation
identifying it as radioactive material and it was allowed to decay in 
storage.   If the source has decayed to undetectable levels can it 
then be disposed of as nonrad material.
