<p><P>PROBLEM TO BE SOLVED: To provide a dosage calculation technique having high reliability even at a place distant from a radiation source and reduced in separation from an observed value, while reducing a calculation time. <P>SOLUTION: This system for calculating a dosage is provided with a means for tracking a simulated scattering process of a radiation in a space ranging from the radiation source to a surrounding surface for surrounding the radiation source, a means for accumulating attribute information of the radiation reached to the surrounding surface by the tracking, a means for referring to contribution information in a prescribed evaluation point of the radiation, according to the attribute information, and a means for integrating the dosages in the evaluation point, based on the attribute information and the contribution information, in the respective radiations on the surrounding surface. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
