Results or findings
Total 37 participants, 28 males and 9 females, mean age 36.97±11.38, range 21 to 60 were included in this study. The demographic characteristics are demonstrated in Fig 1. The age was categorized into four groups based on quartiles, i.e. minimum – Q1, Q1 – Q2, Q2 – Q3, Q3 and above.
The mean knowledge of radiation was 8.11±3.65 (47.70%). Fig 2 shows the frequency of correct response for each question.
Mann Whitney U-test showed there was no statistical significance of knowledge according to gender, U =150.50, p=0.392.
Kruskal Wallis H-test demonstrated there was no statistical significance of knowledge according to age groups, χ2(3) =2.17, p=0.538 and work experience, χ2(2) = 1.75, p=0.417, whereas there was the statistical significance of knowledge according to academic qualification, χ2(2) =13.17, p=0.001.
Pairwise comparison with Bonferroni correction showed that diploma and bachelor’s pair, p=0.033 and diploma and master’s pair, p=0.008 were statistically significant.
Fig 3 demonstrated the mean knowledge score with statistical significance.
