A system and method for waste reclamation by which dissolved molybdenum (Mo) is reclaimed and heavy metals are filtered from process wash water containing Mo for onsite disposal. The system and method reduces byproduct cost by converting liquid byproduct to solid byproduct, while converting dissolved Mo in solution into a solid form capable of being converted to base metal.

A method for producing Actinium-225 from proton spallation of thorium targets via a radium generator. The method includes dissolving a thorium target into a thorium solution, evaporating the thorium solution thereby resulting in a dried thorium salt, reconstituting the dried thorium salt in sulfuric acid for formation of neutral thorium species, passing neutral thorium species through a cation exchange chromatography column for bulk thorium removal, conducting extraction chromatography in a mixed resin bed thereby eluting radium, evaporating the radium containing eluent, reconstituting dried radium, and conducting extraction chromatography to elute a purified radium fraction thereby constructing a radium generator.

METHOD FOR DETERMINATION OF ACTINIUM-227 IN ACTINIUM-225
A method for determination of Actinium-227 (Ac-227) via indirectly produced Ra-225/Ac-225 parent/daughter. The determination of Ac-227 or its decay daughters can be used as a “pre-release” quality control test for total Ac-227 content.
A method for determination of Actinium-227 (Ac-227 ) via indirectly produced Ra- 225/Ac-225 parent/daughter. The determination of Ac-227 or its decay daughters can be used as a "pre-release" quality control test for total Ac-227 content. Method includes : Extracting actinium isotopes from purified Ra-225 to generate Stock A. Resting Stock A to allow Ac-227 to decay to Th-227. Adding a Thorium tracer to Stock A. Chemically isolating the Th-227 and Thorium tracer. Mounting the thorium isotopes to an alpha counting disc. Counting the alpha disc using alpha spectroscopy counting equipment to determined Th-227 quantity and tracer recovery percentage. Determine an amount of Ac-227 by using the counts.
