APPARATUS FOR PRODUCING RADIOISOTOPE AND METHOD OF RECYCLING TARGET

摘要

An apparatus for producing a radioisotope to conduct PET diagnosis for screening cancer or examining brain or heart metabolism. Namely, a technique of providing an apparatus for producing a radioisotope by which the radioisotope can be stably supplied at a high yield and which ensures a long life of a target. Namely, an apparatus for producing a radioisotope having a target (20) containing a feedstock water (W) enclosed therein for forming the radioisotope upon the irradiation with an ion beam (R) that has been accelerated by an accelerator, a transmission foil (22), which forms the boundary between a vacuum area (U) and the feedstock water (W) and through which the ion beam transmits, and a body baseboard (24) forming a space (S), in which the feedstock water (W) is enclosed, together with the transmission foil (22), characterized in that the surfaces of the body baseboard (24) and the transmission foil (22) in the side of the space (S) are made of at least one precious metal material selected from the group consisting of gold, platinum and palladium.
