Naturally Occurring Radioactive Materials definition

Naturally Occurring Radioactive Materials or "NORM" means materials that may contain any of the primordial radionuclides or radioactive elements as they occur in nature, such as radium, uranium, thorium or potassium, and their radioactive decay products such as radium and radon that are undisturbed as a result of human activities. (See USEPA/Office of Radiation and Air, Radiation Protection Division – Technical Report on TENORM from Uranium Mining, vol. 1 and 2 (2006)).
