Actinon
Definition
A historical and scientific term used to designate the radioactive isotope radon-219 (An), a structural intermediate product within the natural decay chain of actinium or uranium-235. It is a heavy, unstable noble gas with an extremely short half-life of approximately 3.96 seconds, emitting high-energy alpha particles before transforming into polonium-215, monitored in nuclear research laboratories for the study of radioactive emanations.
