NORM (Naturally Occurring Radioactive Materials) is acronym generally used for substances in which Naturally Occurring Radionuclides (NOR’s) show up in concentrations above about 0.1 Becquerel per gramme (Bq/g). In the gas and oil industry, the term NORM is commonly used to describe the products and by-products in which the radioactive progeny of the two long-lived parent radionuclides, 232Th and 238U either show up or become enriched due to production or treating processes. During oil and gas production process this progeny may, to some extent, be brought to the surface together with natural gas, with well-fluids Iike natural gas liquids, crude oil and water, and with solid particles.
