This Safety Guide, which is jointly sponsored by the IAEA and the ILO, updates previous guidance material and extends its coverage to include activities involving all raw materials for which radiation protection measures need to be considered, as well as including additional guidance on authorization of mining and processing activities, inspection and compliance. The main purpose of this Safety Guide is to provide practical guidance on meeting the requirements of the Basic Safety Standards as they relate to the radiation protection of workers in the mining and processing of raw materials, and thus to facilitate the preparation and adoption, by Member States, of national and local regulations rules and work procedures in this area of industrial activity. This Safety Guide is aimed at regulatory bodies, operators of mines and mineral processing facilities, health and safety committees, workers and their representatives, and health and safety professionals.
