ORNL Isotopes

On #SingleParentDay, a nuclear science reminder: Some isotopes only exist because another comes first. Neptunium-237 is a parent isotope that's decay chain eventually produces actinium-225, an isotope critical to cancer therapy research.

ORNL is driving the future of #nuclear power by fueling innovation across diverse applications, from advanced reactors to next-gen #nuclearbatteries that can power missions where reliability matters most.
