  • Publication number: 20230210072
    Abstract: A neutron ray irradiation target apparatus 100 of the present invention is used to irradiate irradiation targets (seeds, etc.) with a neutron ray generated by a neutron ray irradiation apparatus. The neutron ray irradiation target apparatus 100 has a holding means 70 for holding the irradiation targets. The holding means 70 holds at least one closed container 30 which can accommodate the irradiation targets 20 stacked randomly and three-dimensionally. In the case where the irradiation targets are stacked three-dimensionally and accommodated in the closed container, the irradiation targets overlapping each other are irradiated with the neutron ray in a chain reaction fashion. The neutron ray irradiation target apparatus 100 can be used in a method for irradiating a large amount of irradiation targets (seeds of crops, etc.) with a neutron ray, while reducing a required time, thereby efficiently inducing mutations in the irradiation targets.
