摘要
以鲤鱼为例建立体素模型,计算水中137Cs对鲤鱼不同组织和器官的外照射剂量转换因子,并与建立的与体素模型尺寸相一致的简化模型、欧盟非人类物种评价方法 ERICA、ICRP 108号报告中参考生物淡水鱼的剂量转换因子估算结果进行了比较。结果显示,在本文的建模条件下,体素模型计算所得的总的剂量转换因子与简化模型的总剂量转换因子的结果接近,低于ICRP 108号报告和ERICA方法所提供的剂量转换因子的结果。
Taking carp as an example, a voxel phantom is built to calculate dose conversion coefficients (DCC) of different organs for 137 Cs. The results were compared with data estimated with a simplified model of same size, the Environmental Risk from Ionizing Contaminants--Assessment and management (ERICA) and those for reference trout in ICRP publication 108. It shows that the total DCC by the voxel phantom is similar to that by the simplified model, and is less than the recommended values of ICRP and ERICA.
