Keywords:PHITS, Polygon, Tetrahedral-mesh, CAD

A function to use tetrahedral-mesh geometry, a type of polygon geometry, was implemented to Monte Carlo radiation transport code PHITS. Tetrahedral-mesh is very useful to describe complex and flexible geometry and geometry data such as CAD is compatible through conversion using softwares. The polygon human phantom, which will be adopted for international radiation protection purpose, can be utilized by this function. The introduction and some calculation examples will be presented.
