In previous study, the sensitivity study of doserate considering uncertainty of concrete mix and deference of water content were implemented. Additionally in this study, the impact to dose rate caused by the gap between average concrete chemical composition and existing ones was evaluated. And the affection of neutron up scatter to doserate was also investigated. These study will be dirtribute as reference data for standard shielding concrete chemical composition.
