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.

The dense z-pinch is considered as the basis for a compact and relatively simple fusion reactor. The pinch is created in a 200 µm diameter vortex of heavy water formed on the axis of a cylindrical pressure vessel of approximately one meter in radius. The water is the electrical insulator, the heat transfer medium, and acts as a continuously replaceable first wall. The pinch is pulsed repetitively at 120 Hz and with an input power of 17 MWe would produce about 500 MWth. The concept makes considerable use of existing pressurized water fission reactor technology. Experiments underway to test the plasma physics aspect of this concept have demonstrated that a pinch carrying 330 kA can be formed in quartz capillaries of diameters between 200–1600 µm which are filled with deuterium at pressures ranging from 80 mm to 20 atmospheres.
