Abstract
Many monitoring and inspecting efforts are intended to include classified nuclear materials. These efforts have often focused on the use of attribute measurement systems to increase confidence that an item is consistent with declarations made about that item. If an item possesses appropriate unclassified attributes (such as exceeding a threshold mass or being metallic), it may be deemed acceptable for the purpose of a monitoring regime. Measurements of the plutonium mass and metal attributes are of particular interest when the plutonium is contained in a storage canister. We present the results of calculations and measurements for the mass and oxide attributes in this geometry.
