Abstract
A radiation irradiation system and a control method therefor. On the basis of weight proportions of elements in a human body and reaction intensities the elements with a neutron and a photon, the element that has influence on simulation calculation results of the neutron and the photon in an application scenario of the radiation irradiation system is screened out, and during a simulation process, only the screened-out element is simulated, so that the calculation speed can be greatly improved, and the calculation time can be reduced.
