Re: Radiation Detector Calibrations

[CCHOGAN@life.uams.edu]

I would be interested in any responses you get on this subject.  We have always
calibrated our instruments in mR/hr with a Cs-137 source.  But no one here uses
Cs-137 and most of our usage is P-32, S-35, P-33 or I-125.  For this reason, 
we are considering calibration of the instrument's CPM scale using a pulser
and then determining the detection efficiency of the individual probes for 
the particular isotopes in use.  Does anyone out there have references
(regulatory or otherwise) that would favor one method over the other?

I am trying to determine the "best" way to calibrate a survey instrument...
