Dose assessment more accurate! Development of detailed polygon-type human models of Japanese

- [Summary of announcement]

- In recent years, human models and simulation calculation technologies used to calculate the radiation exposure dose have progressed dramatically. We have reached a point where detailed exposure dose assessments reflecting the differences in individual physique and posture, which have been difficult in the past, can be made soon.
- The International Commission on Radiological Protection (ICRP) gives a proposal on the need for exposure dose assessments of the stem cell region highly susceptible to radiation based on the latest scientific findings. However, it wasn't possible to assess an exposure dose with the conventional voxel-type human model due to the complex micro-size structure (of the stem region).
- New male (JPM) and female (JPF) polygon-type human models were developed which replicate the complex structures of the eyeball tissues and the stem cell region at a microlevel based on polygon technology and reflect the characteristics of the body physique and the mass of organs of standard Japanese adults (Figure 1).
- From October 24, 2024, the polygon-type human models (JPM and JPF) will be released to the public free of charge on the source code management platform "GitHub web". These models are expected to be applied to exposure dose assessments and radiation protection study in the fields of medicine and nuclear energy.
