ABSTRACT:
A radioisotope production apparatus includes: a linear accelerator for accelerating an ion beam and irradiating a target with the ion beam, radio frequency power supplies for supplying radio frequency waves through coaxial tubes and the linear accelerator, a target shield member containing the target, a first radiation shield member covering the linear accelerator, and a movable second radiation shield member covering the side of target shield member of the linear accelerator between the first radiation shield member and the target shield member. The first radiation shield member is movably divided in opposite directions, respectively, of the axial direction of the linear accelerator from the base point of the connection point of the coaxial tube connected to the linear accelerator.
