| Research Abstract |
A numerical simulation tool is developed. The proposed tool is composed by the behavior of Cs-137 on the surface of building material, movement of Cs-137 accompanied by water flow in porous media, and 1-dimensional point attenuation kernel method. This unique tool can predict the prospective radio-dose impact in houses. On addition to this, for that purpose, atomic compositions and densities of building components commonly used in Japan are collected and make the data-base of gamma-ray shielding performance are prepared by using the Phits codes.
