台灣民眾對於輻射所可能造成的傷害因為知識之不足而越來越感到害怕；醫事放射師因工作的關係，比一般人更有機會接觸輻射，並應接受過良好的輻射教育。本研究目的即在瞭解醫事放射師的輻射安全知識，及其可能影響因素，以便提供相關研究或行政單位參考。
本研究假設是教育程度越高及工作年資越短的醫事放射師會有較佳的輻射安全知識，研究採自行編制問卷，除基本資料外，輻射安全知識題目來源是從相關國家考試題庫中隨機抽出，預試總共在二家準醫學中心取樣30人，研究對象母群體是醫學中心現職的醫事放射師（包含放射診斷、放射腫瘤及核子醫學），總共完成醫事放射師144人，全部採用一對一方式填答，並分析性別、教育程度、工作科室及工作年資與輻射安全知識的關係。
研究結果發現教育程度及工作年資顯著影響醫事放射師輻射安全知識，且達到統計學上顯著相關：教育程度在大學以上者輻射安全知識較專科程度者為佳，但工作年資越久的，其輻射安全知識卻較工作年資短的為差；其餘變項包括性別及工作科室，則未達統計學上顯著差異。
本研究證明學校教育和繼續教育對醫事放射師而言都是相當重要的，專科教育應加強輻射安全知識的相關課程，而在職繼續教育則可提供最新的輻射安全觀念，進而避免醫事放射師工作時受到輻射傷害，並減低病患接受不必要輻射劑量曝露的機會。

People in Taiwan are afraid of radiation injury partially due to distorted radiation knowledge and mis-information. Radiological technologists are routinely exposed to radiation in their work. Radiation technologists should be well-educated in radiation safety. The purpose of the research is to understand the radiation safety knowledge of radiological technologists and the factors that influence this information. The results from this study will offer information for administrative authorities and further research.
In this study, it was assumed that higher-educated radiological technologists with recent employment would have better radiation safety knowledge. A radiation safety knowledge questionnaire was adopted from the radiological technologist board examinations. This questionnaire contained a basic radiation knowledge profile. The pilot study sampled 30 radiological technologists from two pre-medical centers. The radiological technologists working at the department of diagnostic radiology, radiation oncology and nuclear medicine in four domestic medical centers were collected by random sampling. The relationship between the radiation safety knowledge of radiological technologists and the factors, including gender, education level, working place and career period were analyzed. A total of 144 radiological technologists completed the questionnaire through a one-to-one survey method.
The results indicate a significant difference and correlation between radiation safety knowledge, education level and duration of employment. Radiological technologists with a college level education showed better knowledge than those with a junior college level education significantly. The radiation safety knowledge of longer employment was significantly worse. Other variables, such as gender and different department, were not significantly different in radiation safety knowledge.
This study indicates that adequate formal education and continual training in radiation safety knowledge is necessary for radiological technologists. On-the-job training is recommended strongly for radiological technologists in order to avoid occupational radiation injury and decrease the potential of injury for patients.
