Forward calculations with isotropic DS02 fluences and adult male and female phantoms

Individual doses for the Life Span Study (LSS) of atomic bomb survivors have been estimated using the Dosimetry System 2002 (DS02). DS02 estimates individual doses using organ dose database calculated by three age-specific mathematical phantoms (infant, child and adult) developed in 1980s, distance from the hypocenter, and shielding conditions. Nowadays more anatomically realistic phantoms, voxel type and polygon mesh type, have been developed, and the use of these phantoms will improve assessment of organ doses of the atomic bomb survivors. The study compares organ doses calculated using mathematical and voxel phantoms of adult and quantifies dosimetric impacts of the use of the new phantoms on the assessment of organ doses.
