MIRD19 data were derived from MIRD19 (8) for homogeneous activity distributions in cortex and medullae. M19 voxel model is also for homogeneous activity distribution inside a 3-mm voxelized MCNP model of MIRD19 kidney. Heterogeneous activity distribution, given in Table 1, is used in the 3D voxel model, shown in Figure 2. In the 3D voxel model, 3 regions are defined in cortex: JM, medullary rays (MR), and non-MR, with the sum in total cortex.
