THREE-STAGE CARRIER FOR GAMMA RAY IRRADIATION TREATMENT AND GAMMA RAY IRRADIATION TREATMENT METHOD USING THREE-STAGE CARRIER

摘要

A three-stage carrier transported to an irradiation room by transporting means and irradiated with gamma ray sources installed on ray source rack such that a product loaded therein is treated, the three-stage carrier includes a central container in a center of the three-stage carrier; an upper container formed on the central container; and a lower container formed under the central container. Here, the central container, the upper container, and the lower container are partitioned by septum, a height of the three-stage carrier is greater than a height of the ray source lack, and the central container has a height greater than a height of the upper container or a height of upper container.
