MCQ

This document contains multiple choice questions about medical physics and radiation protection. It covers topics like dosimetry, personal radiation monitoring devices, occupational exposure limits, radiation protection of pregnant workers, purposes of personal monitoring, patient radiation protection devices, radiation sensitivity of different cell types, biological effects of different radiation types, and the radiation protection principles of minimizing exposure time, maximizing distance and using appropriate shielding. It suggests including an explanation of the answer to question 15 in a lecture and using question 12 as an exam question.
