That's cool.  I am all for training.  In fact, I wouldn't object to DHS
establishing a facility where hopeful companies try out their equipment
to see if it makes the grade.  But when it comes test time, the
equipment needs to perform in conditions as close to real world as
possible, which is not compatible with "dress rehearsals" and
"calibration" runs.

Mike, that description fits "training" better than "calibration".

I interpreted "calibration" in this case not to be using a known source
to make sure the instrument was operating within expected parameters,
but using the source it was expected to find to make sure it would find
it.  If that is the case, I agree with the auditor that it invalidates
the event as being an actual test of the detector's capabilities.
Unless all smugglers are required to give advanced warning in writing,
so the detectors can be set up for the isotope that will be coming
through.

When was the last time you used a radiation monitor that hadn't first
been calibrated?

         What is the difference between this and outright collusion?
*Is*
there any difference?
