WebThe two most common isotopes of radium in water are radium-226 (the most common) and radium-228. Radium-226 is a disintegration product of uranium-238 and is formed when the nucleus of a helium atom (an alpha particle) is emitted from the nucleus of the decaying thorium-230 nuclide (figs. 2 and 3). Radium-226 has a half-life of about 1,600 years. WebRadium (Ra) is a naturally occurring radioactive element that is present in varying amounts in rocks and soil within the earth's crust.
