KNOWLEDGE OF IONIZING RADIATION HAZARDS AND RADIATION PROTECTION PRINCIPLES AMONG MEDICAL STUDENTS OF QASSIM UNIVERSITY, SAUDI ARABIA

Background: The use of ionizing radiation has evolved significantly since the discovery of X-rays in 1895 to include not only medical purposes but also for security concerns. Despite the significant reduction in radiation dose, ionizing radiation is still a major concern for its potential to cause cancers and birth defects. In this study, we aim at identifying the gaps of knowledge regarding the topic and therefore implement educational activities in order to fill these gaps.

Methodology: cross-sectional study and conducted on 4th and 5th-year medical students of Qassim University. A total of 130 students completed a self-administered questionnaire from both male and female branches have participated in the survey.

Result: large proportion [61.5%] of the participants in this study demonstrated good knowledge of radiation hazards. 61.5% of the study participants thoughts objects insides room do not produce radiation. However, 46.2% highlighted X-ray is more dangerous than gamma. 43.8% of participants expressed that Radian is the DI unit for measuring radioactive materials. Regarding organ protection, 84.6% indicated that the thyroid gland is the most important organ to be protected against when it comes to head and neck radiography.

Conclusion: This study demonstrated good knowledge about radiation protection practices. The study result showed that there is no significant difference in the study participant's knowledge regarding gender and academic level.
