Regarding with standard chemical composition of concrete for shielding calculation,the dose rate fluctuartio has been investigated considering concrete mixture, moisture in concrete, deferential between some concrete chemical composition so far. In this study, based on reserch of various concrete chemical composition, the dose rate fluctuartion is calculated with some typical chemical composition.
