Some materials that are used in various industrial processes, or generated as by-products or wastes, contain naturally-occurring radionuclides in concentrations that can be radiologically significant. If the concentration exceeds certain levels these materials would be subject to regulatory control during transport.

This study examined the transport of such materials in the United Kingdom and it was found that this gives rise to very low radiological consequences.

The International Atomic Energy Agency initiated an international coordinated research programme to examine the transport of naturally occurring radioactive material and this study was a contribution to that research.
