Abstract
A shielding apparatus for a radioisotope production system is provided. The shielding apparatus is capable of being retro-fitted to the housing of preinstalled radioisotope production systems. The shielding apparatus comprises a plurality of shield layers removably stacked on top of a base that is mounted to the top of the housing via spacers defining space or air gap between the base and housing. The shield layers and base are positioned above and extending between the interface between moveable shields and a moveable base of the radioisotope production system, such that the shielding apparatus is positioned within the trajectory of a radioisotope production system beam.
