Radium radionuclides emit alpha and beta particles as well as gamma rays. The radiation emitted from a Radium 226 atom is 96% alpha particles and 4% gamma rays. The alpha particle is the most dangerous particle associated with NORM. Alpha particles are helium nuclei. Alpha particles travel short distances in air, of only 2-3 centimeters and cannot penetrate through a dead layer of skin on the human body. However, some alpha particle emitters are "bone seekers" due to Radium possessing a high affinity for Chloride ions. In the case that Radium atoms are not expelled from the body, they concentrate in areas where Chloride ions are prevalent, such as bone tissue. The half-life for Radium 226 is approximately 1,620 years, and will remain in the body for the lifetime of the human; a significant length of time to cause damage.
