A closure ( 10 ) for shielding, and selectively providing access to, the targeting assembly of a particle accelerator of a radioisotope production system. The closure ( 10 ) includes at least one, and in one embodiment, first and second doors ( 44, 46 ), for selectively covering an opening in the housing of the particle accelerator which provides access to the targeting assembly. A door mounting assembly is also provided for mounting the first and second doors ( 44, 46 ) on the housing of the particle accelerator. In one embodiment the door mounting assembly includes a frame ( 30 ) for being secured about the opening in the particle accelerator accessing the targeting assembly. Further, in one embodiment the frame ( 30 ) and first and second doors ( 44, 46 ) are fabricated of copper.
