A theoretical model for simultaneous mixed irradiation with multiple types of radiation

Several models for the action of mixed irradiation with two types of radiation have been proposed in the last two decades, although the superiority or inferiority of these models is not completely elucidated. However, mixed irradiation is sometimes composed of more than two types of radiation, and for this type of mixed irradiation, no model has yet been proposed. Therefore, I have tried to make a model for this type of mixed irradiation. This paper presents a survival model for simultaneous mixed irradiation with multiple (n) types of radiation, and this model would be helpful for assessing the effects of simultaneous mixed irradiation with multiple types of radiation in nature, accidents, etc.
