Abstract

The dose to active bone marrow resulting from anteroposterior (AP) and posteroanterior (PA) chest examinations was estimated using an Alderson Rando phantom and extruded lithium fluoride dosimeters. The AP projections resulted in a mean marrow dose range of 1.9-2.6 mrad (0.019-0.026 mGy) as compared to doses for PA projections of 3.4-3.8 mrad (0.034-0.038 mGy) for optimally diagnostic exposure taken at 70, 90, and 120 kVp.

摘要

使用阿尔德森·兰多人体模型和挤压式氟化锂剂量计，估算了前后位（AP）和后前位（PA）胸部检查对活跃骨髓造成的剂量。与在70、90和120千伏峰值下进行最佳诊断性照射时PA位投影的剂量（3.4 - 3.8毫拉德，即0.034 - 0.038毫戈瑞）相比，AP位投影产生的平均骨髓剂量范围为1.9 - 2.6毫拉德（0.019 - 0.026毫戈瑞）。
