North Anna is benchmarking the industry on Count Room MCA calibration. 1. Do you calibrate your MCAs annually?
2. What process do you use to calibrate your MCAs? For example ordering sources for each geometry or ordering a single source to verify no significant change in detector efficiencies? 3. Do you install new calibration values after completing detector energy/efficiency calibrations or continue to use the old values if energy/efficiency values have not changed significantly? Thank you in advance for you help! Barbara J.
