For those hysterical ‘oh no not nuclear energy’ fanatics:
Naturally-Occurring Radioactive Materials (NORM)(Updated May 2015)
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.
Radon in homes is one occurrence of NORM which may give rise to concern and action to control it, by ventilation.
In other words, if you’re afraid of radioactive materials just move to another planet.
