DISCUSSION ON THE STANDARDIZATION OF CONCRETE COMPOSITION FOR RADIATION SHIELDING DESIGN II - Evaluation of the effect of the composition variance on the shielding property -

摘要

Radiation Shielding Material Standardization Working Group of AESJ has been organized to establish Japanese standard concrete composition for radiation shielding design. We have collected concrete composition data to organize a representative concrete composition data. Neutron and Gamma dose rates penetrated through several concrete compositions are calculated by one dimensional discrete ordinate code ANISN. Effects of the variation of concrete composition on the neutron and gamma dose are evaluated. In this paper, recent standardization activity is summarized.
