Revised version of Dosimetry System 2002 (DS02R1)

Furuta, Takuya

Nippon Hoken Butsuri Gakkai Homu Peji (Internet), 2 Pages, 2017/10

The current standard of the international radiation protection is determined through life span study of atomic bomb survivors of Hiroshima and Nagasaki, and individual radiation dose estimates for each survivor calculated by Dosimetry System 2002 (DS02). Dose estimates in DS02 are based on input data such as location and shielding condition of the survivor. Therefore accuracy of dose estimates and accordingly that of radiation risk evaluation are largely affected by the accuracy of the input data. In this review, we present an article DS02R1 discussed improvement of the input data of individual atomic bomb survivors for DS02 and its consequence keeping the core system unchanged.

Oral presentation

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

Endo, Akira

no journal, , 

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.
