摘　　要：目的研究和比较水作为血液的辐照吸收剂量测试的替代介质的有效性。方法通过使用Geant4程序模拟计算铯-137放射源分别在水和血液成分中的辐照吸收剂量,分析比较铯-137在水和血液中的辐照吸收剂量的差异。结果铯-137放射源在水和血液中的辐照吸收剂量平均偏差<2%。结论水可以作为血液的辐照吸收剂量测试的替代介质。Objective To analyze and discuss the validity of using water as the blood substitutes in the test of blood irradiation absorbed dose. Methods Use Geant4 program to simulate the absorbed dose of cesium-137 radioactive source in water and blood, and then analyze and compare the difference and equivalent of absorbed dose between water and blood. Resuits The radiation dose error of cesium-137 radioactive source in water and blood is less than 2%. Conclusion Water can be used as the blood substitutes in the blood irradiation dose testing.
