Abstract
The International Labour Office (ILO) International Classification of Radiographs of Pneumoconioses is an instrument intended to "standardize classification methods and facilitate international comparisons of data on pneumoconiosis, epidemiological investigations and research reports" (ILO 2002). The scope and purpose of the Classification are clearly stated in its guidelines: to describe and systematically record radiographic abnormalities seen on postero-anterior chest radiographs due to inhaled dust diseases. It is not designed to defint pathological entities, and it does not take into account working capacity or compensation for disability (JACOBSEN 1991). The initial version of the classification was issued in 1930, with subsequent revisions published in 1950, 1958, 1968, 1971, 1980, and 2000. The first editions were focused on silicosis. In 1958, a single category was included to cover all types and profusions of linear markings. In the 1960s, the International Union Against Cancer (UICC) evolved a parallel system for linear (now called irregular) opacities, mainly spurred by asbestos exposure. In 1968, the UICC and ILO systems were merged for all dust-induced pneumoconioses, with the ILO embracing the UICC ideas (HENRY 2002; ILO 2002; SHIPLEY 1992).
