Naturally occurring radioactive material (NORM)

Naturally occurring radioactive material (NORM) is material found in the environment that contains radioactive elements of natural origin. NORM primarily contains uranium and thorium (elements that also release radium and radon gas once they begin to decay) and potassium. These elements are naturally decaying and are considered a primary contributor to an individual’s yearly background radiation dose.

Where can NORM be found?

NORM is often found in its natural state in rocks or sand. It can also be associated with oil and gas production residue (such as mineral scale in pipes, sludge and contaminated equipment), coal ash (produced from burning coal for energy production) and on filter media (such as the used filters from municipal drinking water treatment equipment). NORM can also be present in consumer products, including common building products (like brick and cement blocks), granite counter tops, glazed tiles, phosphate fertilizers and tobacco products.

Some industries may regularly come into contact with NORM – for instance, those engaged in the production of oil and gas, phosphate fertilizers, forest products and thermal electricity; mineral extraction and processing; tunneling and underground workings; metal recycling; waste management; and water treatment
