Naturally Occurring Radioactive Materials or NORM, are commonly found radioactive materials. The average U.S. citizen is exposed to 360 millirems of radiation a year, most of which comes from background radiation sources. Sources of NORM include the human body, air, soil, peanuts and public water. Activities such as smoking, living in or working in a brick building and having porcelain teeth can increase exposure to NORM. The process of fracking can release NORM from the earth’s surface. If the levels of NORM get above the acceptable background levels then special disposal of these materials is required. Radioactivity levels vary, for example NORM are found in high levels in the Devonian formation in New York where there are high levels of NORM in the soil, water and rocks.[1]
