Question
1. The plans for a small community hospital call for two X-ray rooms. The estimated patient load for each room is 15 patients per day, and each patient will average three films taken at 80 kVp, 70 mAs. What is the projected workload per room? 2. What percentage of the maximum permissible dose (100 mR/wk) will be incident on a control-booth barrier located 3m from the x-ray tube and patient? Assume the x-ray output is 3 mR/mAs and that the weekly beam on time is 5 min at an average 100 mA, a generous assumption. The output intensity of a radiographic unit at patient position is 410 mR (0.1 mC/kg) for a kidney, urethra, and bladder (KUB) examination. What will be the approximate radiation exposure Im from the patient? 3m from the patient? 3.Explanation / Answer
15 patients/day x 5 days/wk = 75 patients /wk
75 patients /wk x 3 films/pt = 225 films /wk
225 films/wk x 70 mAs/film = 15750 mAs/wk
15750 mAs/wk x 1min/60sec = 262.5 mAmin/wk
