NRPB: Broadsheet on Radioactive Minerals
September 24, 2003
The National Radiological Protection Board (NRPB) has updated its "Working with Zircon Sands" broadsheet in the "Radiation at Work Series" to take into account a wider range of minerals containing natural radioactivity. The revised edition contains an introduction to radioactivity, types of radiation and naturally occurring radioactive materials (NORM). Typical concentrations of radioactivity in some geological materials are given, along with information on the potential external and internal radiation hazards involved in working with these materials.
The broadsheet is available at http://nrpb.org .
