Possible CAMRT - QC Exam Questions and
Answers with Verified Solutions | Latest
Updated 2026
What is the intensity of the scatter 0.1% of the intensity of primary beam
radiation 1m from the patient
approximately?
What is the max permissible 100 mR/hr or 1 mGy
leakage (at 1m from x-ray tube)
radiation allowed by a lead-lined x-
ray tube?
Grieving Process (1) Denial
(2) Anger
(3)Bargaining
(4)Depression
(5)Acceptance
What is the result of intensifying Doubles image intensity; allowing tech to
screen speed from 200 to 400? reduce
mAs by half therefore decreases pt. Dose
What grid ratio is most common on 10:1 or 12:1
fixed general radiographic 8:1 up to 90kV
equipment? 16:1 over 100kV
, What grid ratio should be used 5:1 or 6:1
while
on a mobile unit?
What distance does a 8:1 and 16:1 8:1 = 6" (in)
ratio have with air gap technique? 16:1 = 10" (in)
Fluoroscopy Contrast Resolution, Annually
Image Lag, Maximum
Fluoroscopic
Exposure Rate should be tested
how
often?
Fluoroscopic "Image Noise" is Semi-Annually
evaluated how often?
Acceptance Criteria for Image Lag 0.013 inch or smaller
QC?
What assures compliance with Maximum Fluoroscopic Exposure Rate
Entrance Exposure Rates for any
combination of mA and kV?
If Maximum Fluoroscopic ABC (Automatic Brightness Control)
Exposure
Rate QC fails, what test should be
done?
