| Outline of Final Research Achievements |
When radioactive materials are released into the atmosphere due to a radiation accident, the public could be exposed to radiation through inhalation. For the estimation of inhalation dose, it is said that the form of radioactive material has a significant factor. In this study, the development of a calculation tool for inhalation doses depending on the form of radioactive materials was considered. The results in this study could be useful for the appropriate implementation of protective measures (treatment, medication, etc.) according to accurate inhalation doses in the event of an unexpected situation like inhalation exposure accident.

| Academic Significance and Societal Importance of the Research Achievements |
原子力発電所事故等により大気中に放出・拡散された放射性物質は、呼吸によって体内に取り込まれ内部被ばく（吸入被ばく）を引き起こす場合がある。そのような被ばく者に対して適切かつ迅速な処置（安定ヨウ素剤投与、代謝促進薬投与、治療など）を実施し人体への影響を最小限に抑えるためには、吸入被ばく線量を正確に評価することが重要となる。本研究で検討した吸入被ばく線量計算コードは、将来発生するかもしれない吸入被ばく事故等における精密な線量評価に資するものである。
