This study was performed to estimate examination frequency and collective and per caput effective doses arising from medical X-ray procedures in Sudan, 2010. Information was collected from 30 hospitals performing radiography, computed tomography (CT), fluoroscopy and interventional radiology (IR) procedures. The estimated annual number of examinations was 33 million radiographic X-ray procedures (99 %), 0.34 million CT exams per year (14 % paediatrics CT), 0.02 million fluoroscopy and IR procedures. The estimated annual number of examinations was 326 per 1000 people. The estimated annual collective and per caput effective doses from medical X-ray procedures mount 7197 man Sv and 0.18 mSv, respectively. The study offered the first projection of frequency and population dose from medical X-ray examinations in Sudan and provides estimates of the impact of the medical X-ray procedures at the national level.
本研究旨在估算2010年苏丹医学X射线检查的检查频率以及集体和人均有效剂量。信息收集自30家开展放射摄影、计算机断层扫描（CT）、荧光透视和介入放射学（IR）检查的医院。估计每年的检查数量为3300万次放射X射线检查（占99%）、每年34万次CT检查（其中14%为儿科CT检查）、2万次荧光透视和IR检查。估计每年每1000人中有326次检查。医学X射线检查估计每年的集体和人均有效剂量分别为7197人·希沃特和0.18毫希沃特。该研究首次预测了苏丹医学X射线检查的频率和人群剂量，并提供了医学X射线检查在国家层面影响的估计值。
