In the softening process, an ion exchanger in the sodium form is used to remove the calcium and/or magnesium from the water. The chemical nature of radium is such that any ion exchanger that will remove the hardness ions will also remove radium. Figure 2 illustrates that radium removed by ion exchange is related to hardness removal.

Radium is a chemical element with the 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 on exposure to air, forming a black surface layer of radium nitride Ra3N2. All isotopes of radium are highly radioactive, with the most stable isotope being radium 226, which has a half life of 1600 years and decays into radon gas specifically the isotope radon 222. When r
