Abstract
This study aimed at 1) investigating the perception, knowledge and behaviors of radiological technologists on radiation defence and 2) preparing plans to reduce the unnecessary radiation dose on practician, patients and their caretakers. For data collection, a structured questionnaire was used to survey 225 radiological technologists living in downtown Busan. To analyze the collected data, SPSS/PC+ Win 13 version was used. For verification of differences between groups, one-way ANOVA was conducted. In addition, multiple regression analysis was conducted to analyze the impact of general variables (knowledge, education, age and length of service) in radiation safety management perspective. No differences were found in terms of the knowledge on radiation/radioactivity according to educational background, age and length of service. In the perspective of radiation safety management, the highest figures were found among those in their 40s and higher and those with the education of college graduation and higher. As for the correlation between radiation safety management and knowledge on radiation/radioactivity, positive correlations were found in all cases. In addition, analysis on the impact of general variables in radiation safety management perspective indicated that the perception on radiation safety management was higher as the level of knowledge on radiation/radioactivity was higher. The correct radiation/radioactivity management through practician training was necessary to reduce radiation dose on radiological technologists and patients.
본 연구는 방사선사들의 방사선방어에 대한 인식, 지식 및 행위를 조사하여 종사자 본인은 물론 환자 및 환자보호자의 불필요한 방사선피폭을 줄이는 방안을 마련하고자 수행하였다. 자료수집은 구조화된 설문지를 사용하여 부산시내에 근무하는 방사선사 225명을 대상으로 하였다. 회수된 자료에 대한 분석은 SPSS/PC+ Win 13 버전을 사용하였다. 또한 집단 간 차이 검증을 위해 일원분산분석(oneway ANOVA)을 시행하였으며, 일반변인(지식, 학력, 연령, 근무경력)이 방사선안전관리측면에 미치는 영향력을 분석하기 위하여 중다회귀분석(Multiple regression)을 시행하여 검증하였다. 학력, 연령, 근무경력에 따른 방사선/능의 지식은 차이가 없는 것으로 분석되었으며, 방사선안전관리의 경우 40대 이상과 대졸이상에서 가장 높은 수치를 나타냈다. 또한 방사선안전관리와 방사선/능의 지식정도와의 상관관계에서는 모두 정적상관을 나타냈으며, 일반변인이 방사선안전관리측면에 미치는 영향력을 분석한 결과 방사선/능의 지식이 높을수록 방사선안전관리에 대한 인식이 높은 것으로 나타났다. 방사선 종사자 및 환자에 대한 방사선피폭을 줄이기 위해서는 종사자 교육을 통한 올바른 방사선/능의 관리에 있다고 판단된다.
