Radioactive materials which occur naturally and where human activities increase the exposure of people to ionising radiation are known by the acronym 'NORM'. NORM results from activities such as burning coal, making and using fertilisers, oil and gas production. Uranium mining exposes those involved to NORM in the uranium orebody.
