The radiation doses received by patients during 41 barium meal (BM) and 42 barium enema (BE) examinations in two Greek hospitals are presented. Radiation dose was measured in terms of the dose area product (DAP). The effective dose and doses to certain organs were estimated using the ODS-60 software. Mean total DAP values were found to be 25 +/- 11 Gy cm2 for BM and 60 +/- 35 Gy cm2 for BE examinations, whereas the estimated mean values of effective dose were 8.6 +/- 4.0 and 24 +/- 16 mSv respectively. DAP to effective dose conversion coefficients were estimated to be 0.34 mSv per Gy cm2 for BM and 0.41 mSv per Gy cm2 for BE.
本文呈现了希腊两家医院41例钡餐（BM）检查和42例钡灌肠（BE）检查中患者所接受的辐射剂量。辐射剂量以剂量面积乘积（DAP）来衡量。使用ODS - 60软件估算有效剂量及特定器官的剂量。发现钡餐检查的平均总DAP值为25±11 Gy cm²，钡灌肠检查为60±35 Gy cm²，而有效剂量的估算平均值分别为8.6±4.0和24±16 mSv。钡餐检查的DAP与有效剂量转换系数估计为每Gy cm² 0.34 mSv，钡灌肠检查为每Gy cm² 0.41 mSv。
