I would like to present a qualified disagreement with John and Jim for this
specific case of WBC QA/QC.
I agree with Jim's comments that from a diagnostic standpoint more peaks are
better and low energy peaks could be useful. But modern Ge systems are quite
reliable and a competent spectrum
Hi All,
I am retired now, but Diablo Canyon had both an HPGe and NaI body counter.
The HPGe counter has been QC'ed with a Eu-152 source since if was purchased
in the mid-90's. My personal opinion is that a Co-60/Cs-137 source is
really not sufficiently challenging to a HPGe system.
Thanks,
I used 152Eu in the mid 80's with Pilgrim's HPGe WBC.

Eu-152 would be the preferred source. HPIG energy response is slightly
non-linear so the lower energies from Eu-152 are advantageous. Also, the
lower energy peaks provide resolution info that can be useful in recognizing
signal noise.

We have been asked to evaluate whether the Landauer Verifii digital dosimetry
platform would be of any value to implement at Fermi 2. We currently use the
Landauer Inlight Model 2 for our DLR along with Sentinel. Mirion DMC2000's and
3000's are used as SRDs along with the applicable
This benchmark is primarily for those of you using a Germanium based whole body
counter...I welcome feedback from everyone, however
Questions (with Ginna info)
1. What WBC system are you using?
Mirion/Canberra Accuscan-II with dual HPGe detectors
1. What nuclides/peaks are you using to
