Occupational exposure to natural radiation

摘要

The theme of the workshop was the control of exposures received by workers from natural radiation sources. Specifically, workplace exposures from NORM (i. e. industrial materials such as ores and scales containing Naturally Occurring Radioactive Material) and from radon were considered. For completeness, occupational exposures (to aircrew) from cosmic rays were also described, but were not within the main scope of the workshop. The objectives of the Workshop were to consider the following questions: 1. how can the commitment to radiation protection be encouraged and increased?; and 2. how should exposure management (for NORM and radon in the workplace) be improved? As with previous workshops, half the programme time was devoted to Working Group discussions and report backs, so that all participants could consider these objectives, contribute to discussions, and formulate the final recommendations of the Workshop.
