It is a revision of IAEA Safety Series No. 43, which was originallyissued in 1976 by the IAEA and the ILO jointly under the title Manual on RadiologicalSafety in Uranium and Thorium Mines and Mills. This previous editioncovered radiation safety standards for mining and milling, radiation monitoring foroccupational protection, engineering and ventilation control measures, and medicalsurveillance. It is now out of print and its content is not necessarily valid.In 1983, the IAEA, together with ILO and WHO, published the revised versiono f Safety Series No. 26, containing the Code of Practice on Radiation Protection ofWorkers in the Mining and Milling of Radioactive Ores and a Technical Addendum.Safety Series No. 26 contains radiation protection standards and codes used in miningand milling. In 1987 the IAEA published Safety Series No. 82, a Safety Guideon the Application of the Dose Limitation System to the Mining and Milling ofRadioactive Ores. This Safety Guide contains guidance on the application of optimizationprocedures in mines and mills, the technology of protection measures andother aspects such as operational decisions and training of personnel. Safety SeriesNo. 82 also contains examples of the use of optimization at different stages in themining and milling of radioactive ores.This revised version of Safety Series No. 43 has been limited in coverage toradiation monitoring and medical surveillance only, in view of the publication of therevised version of Safety Series No. 26 and Safety Series No. 82. It should be usedin conjunction with IAEA Safety Series No. 9 (1982) on Basic Safety Standards forRadiation Protection, and with Safety Series Nos 26 and 82.Over the past decade there have been significant developments in the techniquesand methods of monitoring radon and radon daughters, thoron and thorondaughters, and radioactive dusts encountered in the mining and milling of radioactiveores. The development of new techniques and methods of measurement has receivedincreased attention owing to the fact that the efficient control of radon and itsdaughters in the mine atmosphere, particularly in underground mines, is a somewhatdifficult task. Another important factor is that epidemiological studies have clearlydemonstrated that the incidence of lung cancers among underground uraniumminers, and also among underground non-uranium miners who were exposed toradon and radon daughters in their occupations, has been higher than that among thegeneral public. The IAEA, ILO and WHO therefore considered it important to
