Assessing the Need for Radiation Protection Measures in Work Involving Minerals and Raw Materials

Any mining or minerals processing operation has the potential to increase the radiation dose received by individuals, due to the fact that all minerals and raw materials contain radionuclides of natural, terrestrial origin. However, only in a limited number of cases does the situation warrant the introduction of radiation protection measures. This publication provides information on the relevant industrial activities, materials and expected exposure levels in order to assist in identifying the activities for which regulatory controls are most likely to be needed and, for such activities, determining the most appropriate regulatory approach. The publication will be of interest to regulatory bodies and other national authorities involved in the application of the standards to work activities involving increased exposure to natural radiation sources, and to operators, workers and their representatives, as well as health and safety professionals engaged in such work activities.
