was conducted using a one-way analysis of variance( ANOVA) and the Tukey honestly significant difference( HSD) post hoc test to compare the MED-5y across different medical professions. Independent Samples T-Test comparing mean radiation exposure by gender. A p-value < 0.05 was considered statistically significant.
3 Results
In this study, a total of 574 medical personnel included in this study, comprising anaesthesiologists( n = 44), cardiologists( n = 120), radiologic technologists( n = 112), nurses( n = 276), and radiologists( n = 22). Across the assessed professions, males formed a majority with 54.68 %( n = 314) compared to 45.32 %( n = 260) females( Fig. 1).
Table 1 shows the AMED across various medical occupations was analyzed from 2018 to 2022. In 2018, anesthesiologists had a mean dose of 0.94 ± 0.16 mSv, cardiologists 2.59 ± 4.86 mSv, nurses 0.82 ± 0.38 mSv, radiologists 0.53 ± 0.33 mSv, and radiologic technologists 0.95 ± 0.61 mSv. By 2019, the mean dose for anesthesiologists increased to 1.13 ± 0.26 mSv, while cardiologists experienced considerable exposure variability( 0.40 – 18.90 mSv). In 2020, all professions except cardiologists reported reduced mean doses, notably nurses at 0.92 ± 0.72 mSv and radiologic technologists at 0.90 ± 0.30 mSv. The year 2021 saw a general decrease in mean doses for most professions, with radiologists noting an increase to 1.10 ± 0.29 mSv. By 2022, anesthesiologists recorded a mean dose of 0.72 ± 0.41 mSv, cardiologists 3.47 ± 7.81 mSv, nurses 1.43 ± 0.94 mSv, radiologists
