Title: Radiation calculation device, radiation calculation method, and radiation calculation program
Inventor: NARITA KOJI
IPC: G01N23/06
Filed: 2015-06-28
Abstract: PROBLEM TO BE SOLVED: To calculate a behavior when a radiation flying from various directions passes through the material.SOLUTION: A radiation calculation device stores a composition and a geometrical structure of the material which a radiation passes through, and stores a physical calculation position which is a position calculating a physical amount of the radiation. A direction by which the radiation is incident on the physical amount calculation position is determined, and the composition and the geometrical structure of the material are obtained along an incident direction from the physical amount calculation position. The behavior of the radiation at the time of passing through the material having this material composition and the geometrical structure is obtained, and the behavior at the physical amount calculation position is calculated based on the behavior in each incident direction. By so doing, since it is enough only to obtain the behavior of the radiation in the incident direction, even when the radiation flying from various direction is calculated, the behavior of the radiation can be calculated by avoiding the situation where the calculation amount becomes excessive.SELECTED DRAWING: Figure 3
