Gamma Spec

[dpharrison@aep.com]

Question for gamma spec SMEs, subject matter experts (which I am not):

You count a sample on a HPGe for a certain amount of time, but it doesn't meet a
specific radionuclide LLD.  You calculate the new time where the LLD will be
met.  Can you, instead of recounting the sample for the entire duration of the
new calculated count time, start the count on top of the original spectrum and
just count for the difference in time between the original count time and the
calculated new time?  (acquire a spectrum on top of the original spectrum)

If so, how?  We use a Canberra mca.
