A robust supply of cerium-134 (Ce-134) is an essential step in advancing the use of alpha emitters for cancer therapy due to its promise as a PET imaging analog for therapeutic actinium-225 (Ac-225) and thorium-227 (Th-227) radioisotopes.

Lacking imageable photons or positrons, Ac-225 and Th-227 alone do not register on imaging scans, meaning clinicians cannot visualize whether associated drugs are working as intended. When paired with the chemically similar Ce-134 (and its positron-emitting daughter radionuclide, lanthanum-134), in vivo characterization is possible.

Cerium-134 is produced using high-energy proton linear accelerators at the Isotope Production Facility at Los Alamos National Laboratory and the Brookhaven Linac Isotope Producer facility at Brookhaven National Laboratory. Together, these sites enable year-round production of this high impact radionuclide.

Cerium-134 has a half-life of 3.16 days to lanthanum-134 and is supplied in a chloride solution of Ce(III) in 0.1M HCl. Produced monthly, it is shipped in a glass crimp-top v-vial.

The Department of Energy Isotope Program is the first global supply chain for Ce-134, enabling emerging technologies and advancing new treatments to combat cancer.
