The NIOSH B Reader Program began in 1974, although it was not until 1978 that the B reader examination was given extensively (Attfield 1992). As a consequence, NIOSH concluded that a proficiency program was needed to provide a pool of qualified readers. However, it was found that readers, despite employing the classification scheme, still disagreed with each other and with themselves to an excessive degree (Felson 1973). The principle intent of the standards was to achieve uniformity in assessing pneumoconiosis across readers. This standard B Reading form was designed to create a standardization so that any certified B Reader can interpret a patient’s x-ray with accuracy and certainty.In 1949, the International Labour Office (ILO) promulgated standards for systematically describing and recording radiographic appearances of certain abnormalities caused by the inhalation of dusts. If some abnormalities are found, a determination must be made for whether there are any other disease processes and whether the patient should see their physician about further action. The Center for Disease Control and NIOSH has created a standard B Reading type form as a simple baseline format for all B Readers to delineate what quality of study it is and analyze the possibility of parenchymal or pleural abnormalities. Florida is an example: a primary group of people subject to pneumoconiosis from silica are people working in the concrete industry. Silica is quite a new standard coming out that will impact states where not much B Reading is required. The original type of B Read had to do with coal miners, however it has since enlarged to include asbestos and silica. B Readers are a type of classification of professionals who, through training and written and oral exams, examines chest x-rays to provide interpretation determining if the patient has an occupational related disease.
