Synopsis
Industrial radiography is a well-established non-destructive testing (NDT) method in which the basic principles were established many years ago. However, during 1993-95 the European Standards Organisa tion (CEN) commenced drafting many new standards on NDT including radiographic methods, and when completed these will replace national standards in all the EC member countries. In some cases these standards vary significantly from those in use in the UK at present. These CEN standards are accepted by majority, not unanimous voting, so they will become mandatory even in countries which vote against them. As most are likely to be legal by the time this second edition is published, they are described in the appropriate places in the text. The most important new technical development is the greater use of computers in radiology. In the first edition, computerized tomography was only briefly mentioned at the end of Chapter 11, as it was then largely a medical method with only a few equipments having found a place in industrial use. The method depends on a complex computer program and a large data store. Industrial equipments are now being built, although their spread into industry has been slow. Computer data storage is also being used for radiographic data. Small computers can now store all the data produced by scanning a radiographic film with a small light-spot, and various programs can be applied to these data.
From the Back Cover
Many engineers who rely on structures or components in the course of their work will know the importance of both quality control and in-service monitoring, to ensure effective and safe operation. Non-destructive testing techniques are vital in helping to achieve these aims. This comprehensive update to the successful first edition focuses on the important field of industrial radiology, one of the most widely used techniques. As well as covering the principles behind industrial radiology it describes the methodology and applications of various techniques and the interpretation of results obtained. The book includes completely new material on analysis of standards, the application of computers, computed tomography, processing and automated interpretation of digitized images, and backscatter methods. Industrial Radiology will be invaluable to quality control engineers, metallurgists, and non-destructive testing personnel in many areas of industry, as well as to academics studying defect assessment and behaviour in materials.
