ABSTRACT

We evaluated medical exposure and risk estimation during routine radio-diagnostic examinations in Agadir City during the year 2012. The frequency data were collected from four main Radiological departments of the city performing radiography as well as computed tomography (CT) procedures. The estimated annual number of examinations was approximately 100.000. Eighty percent of diagnostic examinations were conventional radiology procedures while CT exams represent only 20%. The evaluated annual number of examinations was 206 per 1000 people. The estimated annual collective and per inhabitant effective doses from medical X-ray procedures mount 23,207 man Sv and 0.24 mSv, respectively. These results allow us to classify Agadir City at healthcare III according to UNSCEAR classification. As for the average effects during medical exposure, it is 132 10⁻⁷ and 5 10⁻⁷ additional cancer risks and the hereditary effects, respectively. The study presented the first assessment of frequency and population dose from medical expositions in Agadir City and it provides estimates of the impact of the medical x-ray procedures.

摘要

我们在2012年的阿加迪尔市例行放射诊断检查中评估了医疗暴露和风险估计。频率数据是从该市四个主要放射学部门进行放射线照相和计算机断层扫描（CT）程序收集的。估计每年的检查次数约为100.000。80％的诊断检查是常规放射检查，而CT检查仅占20％。评估的年度考试数量为每千人206次。通过医学X射线检查得出的估计年度集体有效剂量和每位居民有效剂量分别为23,207人Sv和0.24 mSv。这些结果使我们能够根据UNSCEAR分类对医疗保健III的阿加迪尔市进行分类。至于医学接触期间的平均影响，则为132 10^-7和5 10 ^-7分别增加了癌症风险和遗传效应。该研究对阿加迪尔市医疗博览会的频率和人口剂量进行了首次评估，并估计了医疗X射线程序的影响。
