A method for producing 225.sup.A including: a method (X) for purifying a .sup.226Ra-containing solution, including an adsorption step of allowing a .sup.226Ra ion to adsorb onto a carrier having a function of selectively adsorbing a divalent cation by bringing a .sup.226Ra-containing solution into contact with the carrier under an alkaline condition, and an elution step of eluting the .sup.226Ra ion from the carrier under an acidic condition; a method for producing a .sup.226Ra target, including an electrodeposition liquid preparation step of preparing an electrodeposition liquid by using a purified .sup.226Ra-containing solution obtained by the method (X), and an electrodeposition step of electrodepositing a .sup.226Ra-containing substance on a substrate by using the electrodeposition liquid; and a step of irradiating a .sup.226Ra target produced by the method for producing a .sup.226Ra target with at least one selected from a charged particle, a photon, and a neutron by using an accelerator.

To obtain deuterium in a gas state from a mixed gas of hydrogen and deuterium at a low cost.

A first electrode 11 is an electrode made of a metal allowing hydrogen (H component and D component) to permeate therethrough (hydrogen permeable metal), and the hydrogen permeable metal is Pd, for example. H ions and D ions having permeated through the first electrode 11 flow to the side of a second electrode 12 in a proton conduction layer 20. When the first electrode 11 is used as an anode and the second electrode 12 as a cathode, H ions and D ions flow in the proton conduction layer 20 from the left to the right in the drawing. In that case, hydrogen component in an input gas is more likely to flow into an atmosphere on the cathode side than deuterium component, and an H/D composition ratio accordingly becomes higher in a product gas than in the input gas. In an exhaust gas extracted after H and D components in the input gas are thus consumed, D component has been enriched.

An air filter system for a utility vehicle includes a filter housing, a coarse filter located on an inlet side and accommodated in the filter housing, a fine filter arranged downstream in a filter operating direction of an airflow to be cleaned, and a cleaning arrangement accommodated in the filter housing for purging dirt particles separated at least in the fine filter counter to the filter operating direction.

A paint booth filter assembly has a housing defining an interior having a securable lid, a shop vacuum exhaust attachment point, and a device exhaust. The device exhaust is secured within the lid. Secured within the interior of the housing is a plurality of removable air filters, having different levels of filtration.

An apparatus and method for separating tritiated water (HTO) and/or heavy water (D20) from light water (H2O). A disposable, dense, plastic filter mesh is disposed within a cylinder which is configured to rotate. Chilled heavy water is pumped into the rotating cylinder. Tritiated heavy water, which is preferably frozen, is pressed to the interior wall of the cylinder which is lined with the filter mesh. The heavy water becomes affixed to the mesh, and light water is drained from the cylinder to be reused as coolant. The mesh filter, when needed, is safely disposed in accordance with industry guidelines. The mesh filter is then replaced with a new iteration of the filter.

The invention relates to isotope separation methods, and methods for separating isotopes with low energy consumption, demonstrated using hydrogen isotopes. Also described are methods for enriching or depleting the isotope present in the hydrogen gas/vapour feed e.g. for tritium removal, tritium enrichment and deuterium enrichment, by arranging a series of cells in a cascaded configuration.

A process and system for treating fluid comprising water, radioactive particulate, dissolved ions, and a neutron absorber are provided. The fluid is received from a cutting zone for recover), of radioactive components. The process comprises receiving a fluid in a crystallization unit, the fluid comprising the water, the radioactive particulate, and the neutron absorber dissolved in the fluid; cooling the fluid below a freezing point of the fluid to form a first crystal comprising the water and to form a second crystal comprising the neutron absorber, the second crystal having a greater density than the first crystal; and separating the first crystal from the second crystal, the radioactive particulate, and the dissolved ions.

A liquid phase catalytic exchange column with a catalyst is configured to receive hydrogen gas. The system uses the catalyst to exchange the hydrogen gas with the tritiated source yielding HT gas and tritiated water. The system monitors tritium content of the tritiated water. When a predetermined tritium level is detected, the tritiated water is released. The system also includes a gaseous permeation system comprising a permeable barrier for the selective extraction of gases.
