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.

Physics similar to the r-process mechanism of forming heavy elements in core-collapse supernovas is invoked to explain the recent observation of nuclear transmutations in thin-film nickel coatings during electrolysis.It is suggested that electrolysis could catalyze weak interactions of the electron capture type in thin films, resulting in an enhanced rate for the weak capture of electrons by protons to form real or virtual neutrons. These could subsequently be absorbed by the nuclei in the metal, and the neutrinos created to satisfy conservation laws would escape detection. The neutron-rich nuclei could stabilize by various beta decay channels similar to the r-process, and this model could explain the observed transmuted elements as well as the absence of radiation.
