Patent ID: 8754387

Claim:
A radioactive material handling assembly, which includes an outer housing; an inner cell which defines a radioactive material containment/handling chamber and which is individually removably mountable inside the outer housing, the inner cell being complementary in shape to the outer housing when both are seen in horizontal section such that, when the inner cell is mounted inside the outer housing, a plurality of walls of the inner cell are adjacent corresponding walls of the outer housing, the inner cell being interchangeable with a plurality of other inner cells which are individually removably mountable inside the outer housing, with at least one of the outer housing and the inner cell being predominantly of a shielding material which is opaque to radioactivity; and at least two handling units configured to operate from outside the inner cell to handle radioactive materials located in the containment/handling chamber, the at least two handling units being mounted to respective walls of the inner cell, which walls are angularly spaced relative to each other about a vertical line of intersection between the walls or projections thereof such that the handling units are thus also angularly spaced from each other, when the inner cell is seen in plan view.
