The third part was about the percepons and acons with 10 quesons each. The data was stascally analyzed byt-test, ANOVA and I-P analysis.Results: First, the more educaon the study subjects received, their knowledge of radiaon increased even though the result was not stascally significant. Second, there was a stascally significant difference in relaon to the gender and the age group in safety management pracces. The degree of safety management pracce was higher among the men than the women.Third, there was a stascally significant difference at the significant level of 5 percent in all 10 quesons on the radiaon safety management and the degree of pracce.Conclusion: Since there is a growing importance on the radiaon safety management, it is imperave to tailor educaonal programs to trainees’ gender, age, educaonal level and duty in order to make the educaon program for radiaon professionals more teleological.
