QSA Global, Niowave to collaborate on Ac-225 production using Ra-226
QSA Global, a provider of radioisotope products, and Niowave, a Michigan-based producer of medical radioisotopes, announced that the companies will codevelop a scalable radium purification process using Niowave’s radium-226 processing technology to meet the demand for actinium-225, an alpha-emitter used in the treatment of cancer. According to the companies, the strategic partnership marks a significant advancement in the field of radiopharmaceutical technology, enhancing the supply chain for critical radioisotopes, including Ac-225.
Niowave uses a closed-loop cycle to produce high-purity Ac-225 and other alpha emitters from Ra-226 using a superconducting electron linear accelerator. According to the company’s website, the electron beam impinges on a photon converter to irradiate the Ra-226, inducing a photon-neutron reaction to Ra-225, which decays to Ac-225.

U(IV) can be photochemically produced in tri-n-butyl phosphate solutions from uranyl nitrate and used to reduce Pu(IV). Nitrite production can be controlled by filtering out light having wavelengths of <350 nm and by keeping the temperature of the reaction mixture below 10°C. Another product of the photolysis, di-n-butyl phosphate, can interfere with the reduction, but no effect was apparent in our experiments. Conventional solvent cleanup procedures should remove photolysis side products. The application of this process to the reprocessing of nuclear fuel would require commercially available light sources that can be located outside the hot zone of the plant and a reactor vessel with windows within the hot zone.
