Analytical Methodology for the Determination of Radium

Radium is an alkaline earth metal with the atomic number 88, belonging to Group IIA in the Periodic Table. It has more than 20 isotopes, all of them radioactive. Two radium isotopes, 226Ra and 228Ra are very significant from a radiological protection viewpoint due to their relatively long halflives, presence in nature, and high dose conversion factors. Radium was discovered in 1898 by Marie
