For TLD processors, I appreciate your answer to the follow 2 questions:
1.  Do you perform a physical inspection of each TLD when you do initial
element correction factor calibration?
2.   Do you perform a physical inspection of each TLD when you do element
correction factor re-calibration?

We do a 100% visual inspection prior to initial calibration.  We do not do
an inspection specifically for recalibration .  However, we do a cursory
inspection of all dosimeters upon receipt from clients, and a more detailed
inspection whenever a glow curve anomaly indicates a potential problem.
