The objective of this study was to evaluate the potential risks encountered during X-ray training in radiology education. 10 exposure scenarios were selected by interviewing the radiation experts who they are professors having roles in the X-ray training. Fourteen organ doses and 13 tissues (weighted per ICRP 103 Publication) were measured with glass dosimeters (GD-352M) and a Rando phantom. Of 270 total organ doses (27 tissues with 10 projection methods) measured, 162 organ doses (60%) were <0.3 mSv; 206 organ doses (76.3%) were <1 mSv. The cumulative effective doses of 10 projection methods resulted in 5.71 mSv, after consideration of tissue weighting factors. Except in human radiography for education purposes, radiation exposure risk is low. The procedure is dangerous to the human body undergoing radiography, so the risk is not justified.
