Tenth meeting of the task force on Shielding Aspects of Accelerators, Targets and Irradiation Facilities Particle accelerators have evolved over the last decades from simple devices to powerful machines and are having an increasingly important impact on research, technology and lifestyle. Today they cover a wide range of applications including Material Science and medical applications. In recent years, requirements from new technological and research applications have emerged and the number of accelerator facilities in operation, being commissioned, designed or planned has significantly increased. Their parameters (such as the beam energy, beam currents and intensities, targets composition, etc.) vary widely giving rise to new radiation shielding aspects and problems. The activities of the Task Force on Shielding Aspects of Accelerators, Targets and Irradiation Facilities (SATIF) are jointly sponsored by the OECD Nuclear Energy Agency (NEA) and its Nuclear Science Committee (NSC), the Radiation Safety Information Computational Center (RSICC) of ORNL, The Division of Radiation Science and Technology of Atomic Energy Society of Japan, and CERN. The main objectives of the SATIF Meetings are to: * Promote the exchange of information among experts in the field of accelerator shielding and related topics, * Identify areas where international co-operation can be fruitful and * Carry on a program of work in order to achieve progress in specific priority areas.
