Abstract: Background: Protecting patients reproductive organs from unnecessary radiation is paramount during anterior-posterior (AP) pelvis radiography. Therefore, assessing patients’ dose is necessary to ensure that the doses are within recommended levels. Objective: This work is aimed at investigating patients’ radiation dose undergoing AP pelvis x-ray examination in selected hospitals of Al Najaf. Material and Method: Patients’ doses were assessed for 93 patients. The Entrance Surface Dose (ESD) was calculated through the knowledge of X-ray tube output and exposure factors. The X- ray output was measured using a calibrated dosimeter for each X-ray tube. Seven X-ray tubes were used to assess the patients’ ESD. Exposure factors (e.g. tube potential (kVp), tube loading (mAs) and X-ray source to image detector distance-SID (cm)) were recorded for each patient. This data was used to calculate the ESD taken into account the backscatter factor. Four main hospitals were selected in this study, namely, Al Sadder (ASTH)), Al Hakeem (AHGH), Al Furat (AFH) and Al Zahraa(AZH). Results: The mean ESD value for AP pelvis X-ray examination was ranged from 0.81± 0.16 mGy to 3.4±0.36 mGy across all hospitals. The corresponding means of each of kVp used for this examination was ranged from 73.3 to 87.3 kVp; mAs: ranged from 13.6 to 35.38 mAs and for the SID the range was between 100 and 123.07 cm. The value of max/min of the ESD was ranged from 1.5 to 3.3 across different hospitals Conclusion: The results demonstrate a clear variation in patient dose and exposure factors set among the selected hospitals. These values (i.e. ESD) were seen to be slightly comparable to those values of the UK (Survey-2010, 3.2 mGy) and were higher than those reported by certain countries (e.g. Iran, Sudan etc.). Therefore, a periodic checking together with conducting a quality control testing is highly recommended.
