NORM is a radioactive material that exists in nature as a byproduct of human life. NORM can be found in the air, water, soil, rocks, and plants.

Furthermore, TENORM refers to naturally radioactive materials that have been concentrated or increased in content as a result of non-nuclear industrial activities that use raw materials from the earth's crust (Technologically Enhanced Naturally Occurring Radioactive Material).

Non-nuclear industrial sectors that have the potential to have TENORM exposure include:

1. Oil and gas
2. Phosphate and Potassium Fertilizer
3. Metal Mining (Iron, Copper, Gold, Aluminum, Tin)
4. Coal and Geothermal
5. Pulp and Paper
6. Bottled Drinking Water and Natural Water Sources
