    Abstract: A portable system for measuring airborne radionuclides from a target environment can include a primary gas flowpath including a cartridge dock. At least a first filter cartridge may be connectable to the cartridge dock and may include a cartridge gas inlet sealingly connectable to the sample supply port, a cartridge gas outlet sealingly connectable to the exhaust port; and a cartridge flowpath extending therebetween. The cartridge can include first and second filter chambers housing first and second filters. A gamma detector apparatus may be positionable adjacent the first filter cartridge when the first filter cartridge is connected to the cartridge dock and is configured to detect radiation emitted from the first filter and to detect radiation emitted from the second filter, and to generate a sensor output signal in based on the detected radiation.

    Abstract: A method of detecting a material with a high atomic number, including positioning a test object in a muon detection apparatus; gathering a set of test data; reconstructing a set of test muon tracks; identifying a set of outlier muon tracks having large scattering events; identifying an outlier spatial domain region; determining outlier region scattering density estimates; determining if the outlier region scattering density estimates are indicative of the presence of the material with the high atomic number; generating a detector notification, when the outlier region scattering density estimates are indicative of the presence of the material with the high atomic number; and providing the detector notification to a user. A system for detecting a material with a high atomic number may include a muon detection apparatus and a processing system communicatively coupled to the muon detection apparatus and including at least one processor operable to generate a detector notification.

    Abstract: A system for monitoring ionizing radiation in a target area, the system may include a first plurality of consumable nodes deployable within the target area to be exposed to the ionizing radiation. Each consumable node may be progressively damageable over a monitoring time as a result of exposure to the ionizing radiation. A base station may be operable to detect an amount of radiation damage sustained by the consumable nodes and to determine a dosage of ionizing radiation received by any one of the consumable nodes based on a pre- determined correlation between the dosage of ionizing radiation and the amount of radiation damage sustained by the consumable node.

    Abstract: A method for hydriding a material, such as a metallic or metal alloy, using coulometric titration. The method comprises placing the material to be hydrided inside a reaction furnace; introducing a flow of a gas mixture comprising hydrogen and optionally an inert gasto a first coulometric titration cell upstream of the furnace, through the reaction furnace, and into a second coulometric titration cell downstream of said furnace; heating the upstream and downstream coulometric titration cells; applying a current of oxygen ions to the gas mixture flow of the downstream coulometric titration cell under conditions effective to convert H 2 in the downstream coulometric titration cell to H 2 O ; and monitoring the current of oxygen, allowing the material to absorb a desired amount of H 2 . The reduction in the current of oxygen can be monitored in real time to quantify the amount of hydrogen absorbed.
