Lecture Abstract: ANSI Standard N43.1, Radiological Safety for the Design and Operation of Particle Accelerators
L. Scott Walker and

In 1994, an ANSI committee was formed to draft a standard on the radiological safety for the design and operation of particle accelerators. Compared to the old standard, the new standard is aimed at a broader application, up-to-date requirements, and recommendations for best practices. The new standard uses a hazard-based, graded approach to address radiation safety programs for nearly all accelerators with various energies and applications (excluding medical accelerators covered by another standard). Chapter topics include the overall radiation safety program, strong hazard identification, safety analysis and safety envelope development, the radiation safety system for protecting workers and public from prompt radiation hazards, access control systems and radiation containment systems (passive shielding), accelerator operational issues related to safety, interlock bypasses, operational radiation safety, radiation measurements, decommissioning, and training.
