WebApr 9, 2024 · All of the isotopes of radium are highly radioactive and the most stable isotope is radium-226 that has a half-life of 1600 years and decays into radon gas (specifically the isotope called radon-222). When the element radium decays, it yields ionizing radiation as a product that can excite the fluorescent chemicals and cause radioluminescence.
