目的：探讨北京地区放射诊断检查对成年受检者的辐射剂量水平。方法选取北京市城区与远郊共10个区域的30家不同级别医疗机构，以1182例X射线摄影、542例乳腺摄影和410例CT检查为研究对象，测读不同投照部位下照射野内受检者/模体所受的辐射剂量。结果普通X射线摄影、CR摄影和DR摄影受检者剂量范围分别为0?4～24?1、0?3～13?9、0?1～15?9 mGy；乳腺受检者乳腺腺体平均剂量为0?3～5?4 mGy；CT受检者CTDIw值为28?1～96?3 mGy、CTDIvol值为7?0～23?4 mGy、DLP值为162?2～898?1 mGy·cm。结论个别放射诊断检查受检者所受辐射剂量高于国标中医疗照射指导水平值，应引起注意。

Objective To investigate the radiation dose levels to the adults examined from diagnostic exposure in Beijing. Methods The radiation doses to the examined individuals were measured by using individual diagnostic radiology equipments in 30 random hospitals from a total of 10 districts and suburban areas, including 1 182 samples of X-ray photography,542 samples of mammography and 410 samples of CT examination. Results 2 134 samples were measured in this study. The dose ranges of X-ray photography, CR, and DR were 0?4 -24?1, 0?3 -13?9 and 0?1 -15?9 mGy, respectively. The average dose range of glandular breast was 0?3-5?4 mGy. In 410 CT samples the value of CTDIw , CTDIvol and DLP were 28?1 - 96?3 mGy, 7?0 - 23?4 mGy, and 162?2 - 898?1 mGy·cm, respectively. Conclusions Several dose levels from diagnostic examination were higher than guidance level for medical exposure in GB 18871-2002,which should be noted.
