the process by which instruments and equipment are maintained to operate within
normal tolerance limits is called: - ✔✔Quality control

2. minimum response time
3. density control functions - ✔✔1, 2, and 3
To insure that protective apparel is functioning properly protective aprons and gloves
should be... - ✔✔radiographically inspected at least once each year

image receptor
which of the following devices is used in a quality control program to check the
exposure rate of a radiographic or fluoroscopic unit? - ✔✔mR / mAs meter
