Knowledge Of Medical Students On Hazards Of Ionizing Radiation

Abstract

Background: The use of the ionizing radiation in the medical practice has evolved since its beginnings. Their benefit for the patient is considerable in term of comfort, diagnostic and therapeutic effectiveness. It is estimated that 30% to 50% of critical decisions in medical approaches is based on x-ray examination. Using the X-ray as a diagnostic means by clinicians requires appropriate and accurate knowledge about its advantages and negative biologic effects.Purpose: to evaluate the knowledge of medical students in clinical courses in Birjand University of Medical Sciences on ionizing radiation hazards.Methods: In this cross-sectional study, knowledge of medical students (in clinical courses) on 3 categories ( of basic principles of radiobiology, radiation protection and practical issues in radiation protection) assessed by a 20-item questionnaire which its reliability and validity had been well established. chi-square and independent-t tests were employed toanalyze data gathered via these questionnaires.Results: Total number of medical students involved in this study was 100. Mean knowledge score was 9.07+!-2.1 (for clerkship students,p
