The main purpose of this study was to determine the diagnostic reference level (DRL) for routine digital radiography examinations in Mazandaran province.
Thirteen digital radiographic examinations at 18 high-patient-load radiography centres were investigated. The indirect dosimetry method was performed based on the IAEA report. Average entrance skin dose (ESD) and the third quartile of ESD as the DRL were evaluated from the measurement made by a semiconductor dosemeter.
DRL for the examinations of digital radiography was obtained as: Skull (postero-anterior [PA]): 2.2, skull (lateral [LAT]): 2.4, cervical spine (antero-posterior [AP]): 1.6, cervical spine (LAT): 1.7, thoracic spine (AP): 3.6, thoracic spine (LAT): 9.9, lumbar spine (AP): 5.3, lumbar spine (LAT): 11.8, chest (PA): 1.4, chest (LAT): 2.1, abdomen (AP): 4.3, pelvis (AP): 3.2 and hip (AP): 2.1 mGy.
Although DRL was not higher compared with the international organisations' levels, it can be reduced by adequate training of radiographers.
本研究的主要目的是确定伊朗马赞达兰省常规数字化放射摄影检查的诊断参考水平(DRL)。
对 18 个高患者负荷放射摄影中心的 13 项数字放射摄影检查进行了调查。根据国际原子能机构的报告,采用间接剂量测定法。通过半导体剂量计测量,评估平均皮肤入口剂量(ESD)和 ESD 的第三四分位数作为 DRL。
获得的数字化放射摄影检查的 DRL 为:颅骨(前后位 [PA]):2.2,颅骨(侧位 [LAT]):2.4,颈椎(前后位 [AP]):1.6,颈椎(侧位 [LAT]):1.7,胸椎(AP):3.6,胸椎(LAT):9.9,腰椎(AP):5.3,腰椎(LAT):11.8,胸部(PA):1.4,胸部(LAT):2.1,腹部(AP):4.3,骨盆(AP):3.2 和髋关节(AP):2.1 mGy。
尽管与国际组织的水平相比,DRL 没有更高,但通过对放射技师进行充分的培训,可以降低其水平。
