During the annual physics survey, must AEC performance be tested for all equipment configurations used clinically by the facility or can it be limited to the contact configuration? What action limits apply?
During the annual physics survey, AEC performance in the contact configuration must be tested. The medical physicist does not have to test the other clinically used equipment configurations during the annual physics survey, see guidance on determining AEC performance during equipment evaluations. In the contact configuration, the action limit requires maintenance of the film optical density (OD) over the 2-6 cm thickness range within +/- 0.30 OD (+/- 0.15 OD after October 28, 2002) of the mean.
