Recertification of Calibration Sources

[Kelly Ausbrooks <ausbrookskl@yahoo.com>]

Radsafers,
   I'm looking for references which specifiy calibration frequencies
for sources used to calibration instrumentation.  Basically, we
looking for information which may cause us to modify our
recertification frequency for type 1 sealed sources (i.e. anodized,
plated, mylar covered, etc).  Note, our sources have been procured
from commercial vendors and are NIST traceable.

Thanks in advance.
