Paper Abstract

In 1969 Congress passed the Federal Coal Mine and Safety Act, Public Law 91-173. This law is sometimes referred to as the Pneumoconiosis law or the "Black Lung" law. It called for periodic radiographic examination of the chests of all coal miners working in underground mines. This law was unique in that it called for multiple readings of the radoigraphs, the second reading to be made by a radiologist not associated with the facility where the radiograph was made. The great variation in the radiographs received led to a need for greater uniformity in the radiographs. A Quality Control Group was set up in an attempt to accomplish this objective. So far as we know this was the first general use of the term "Quality Control" in radiological terminology. The term or idea caught on and in the last couple of years it or its equivalent, Quality Assurance, has become an In subject. No meeting involving radiographic procedures has been without one or more presentations using one of these terms as the subject of the presentation.
