Evaluation of effective dose during X-ray training in a radiological technology program in Korea

Abstract

A B S T R A C TThe 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. Fig. 8.

“…Thus, frequent monitoring of doses is required to ascertain the occupational safety of workers. Similarly, the study conducted by Ko et al [2] suggested that awareness of radiation dose levels, determinants of dose, and protective measures to reduce dose can be improved by providing regular training in radiation protection. However, the magnitude of the individual dose is defined by the nature of the procedure, the individual workload, the level of radiation protection measures, or the methodology of the assessment [9].…”

“…Diagnostic investigations involving ionizing radiation in medical radiology facilities are continuously increasing [1]. The medical personnel involved during examinations are exposed to ionizing radiation and have become a critical feature as it raises concern about the potential risk posed by radiation [2] . Occupationally exposed workers have to abide with radiation protection principles as described in the International Commission for Radiological Protection (ICRP) so as to prevent deterministic effects and minimize the stochastic effects [3].…”

“…Even tiny doses of ionizing radiation can raise likelihood of long-term consequences such as cancer [1][2] . By lowering radiation dose given to patients in accordance with the medical use of radiation, radiologic technicians are trying to improve public health care 3 .…”
