Over the last 50 years particle accelerators have evolved from simple devices to powerful machines, and will continue to have an important impact on research, technology and lifestyle. Today, they cover a wide range of applications, from television and computer displays in households to investigating the origin and structure of matter. It has become common practice to use particle accelerators for material science and medical applications. In recent years, requirements from new technological and research applications have emerged, giving rise to new radiation shielding aspects and problems. These workshop proceedings review recent progress in radiation shielding of accelerator facilities, evaluating advancements and discussing further developments needed with respect to international co-operation in this field.

"Particle accelerators are used today for an increasing range of scientific and technological applications. They are very powerful tools for investigating the origin and structure of matter, and for improving understanding of the interaction of radiation with materials, including the transmutation of nuclides and the beneficial or harmful effects of radiation. Particle accelerators are used to identify properties of molecules that can be used in pharmacy, for medical diagnosis and therapy, and for biophysics studies. Particle accelerators must be operated in safe ways that protect the operators, the population and the environment. New technological and research applications give rise to new issues in radiation shielding. These workshop proceedings review the state of the art in radiation shielding of accelerator facilities and irradiated targets. They also evaluate advancements and discuss the additional developments required to meet radiation protection needs."--OECD
