- Radionuclide Basics: Radium | US EPARadium (chemical symbol Ra) is a naturally occurring radioactive metal. Radium is a radionuclide formed by the decay of uranium and thorium in the environment. The most common. of radium are Ra-226 and Ra-228. Radium-226 is part of the uranium. Radium-228 and Ra-224 are part of the thorium decay series.
- Radium - WikipediaRadium is a chemical element; it has symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) upon exposure to air, forming a black surface layer of radium nitride (Ra 3 N 2).
