Ra-226 has been used in numerous applications following its discovery over 100 years ago. At the beginning of the 20 th Century, radium was a popular additive in consumer products such as toothpaste, hair creams, and even food items due to its supposed beneficial health properties.
Radium is a chemical element with 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 almost colorless, but it readily combines with nitrogen (rather than oxygen) on exposure to air, forming a black surface layer of radium nitride (Ra 3 N 2).adium nitrate (Ra(NO 3) 2) is a white compound that can be made by dissolving radium carbonate in nitric acid. As the concentration of nitric acid increases, the solubility of radium nitrate decreases, an important property for the chemical purification of radium.
