Description
M. V. Suryanarayana, Dipjyoti Balo Majumder, and M. Sankari model a laser route in 2026 for enriching erbium-169, a medical isotope whose decay profile resembles the cancer therapy workhorse lutetium-177. Lutetium supply is squeezed because its parent isotopes are hard to enrich. Erbium-169's longer half-life also eases shipping to remote hospitals.
Their three-step laser isotope separation analysis, built on density matrix math, varied atomic, laser, and beam settings to tune yield. The math suggests making 30 to 300 daily doses at 7.4 gigabecquerels each, with very high specific activity. The scheme works with medium-flux reactors, giving hospitals a backup supply line without scarce high-flux plants.
