Sealed Source Definition

[TSNKW@CCMAIL.CECO.COM (KIT T. WEAVER)]

     I personally use the definition of sealed source given in Reg Guide 
     10.11 where it states, "... a sealed source is radioactive material 
     that is sealed in a protective envelope (capsule), contained in a 
     foil, or plated on an inactive surface.  The term 'sealed source' or 
     'source' includes the radioactive material and its confining barrier, 
     i.e., the capsule, foil, or plated surface.  The confining barrier is 
     relied on to prevent dispersion of the radioactive material under 
     normal conditions for use of the source and most accident conditions."
