All matter is made of atoms that are composed of protons, neutrons and electrons; natural radioactivity arises from the decay of nuclei in atoms (ACSSU177).
Atoms make up everything. The geological formations that contain oil and gas also consist of naturally occurring radioactive materials. Elements are combined to create compounds, such as steel, which is a major output of the resources sector.
