ANSI Standard N 43 1 2011 Radiation Safety

ANSI Standard N 43. 1 (2011): "Radiation Safety for the Design and Operation of Particle Accelerators" 1 Liu and James C. Lawrence S. 1. SLAC National Accelerator Laboratory, CA, USA 2. Brookhaven National Laboratory, NY, USA 2. Major Elements 1. Introduction ANSI: American National Standard Institute New ANSI N 43. 1 published in November 2011 N 43. 1 was developed to address the hazards and controls for accelerators in current technical, operational and regulatory environment. Goal: provide a consistent and sound radiation protection framework for accelerator community. Chapter 1 — Purpose, Scope and Introduction Chapter 2 — Acronyms, Abbreviations, and Definitions Chapter 3 — Radiation Safety Program 3. 1 General 3. 2 Organization and Administration 3. 4 Design and Implementation of Safety Controls and Monitoring 3. 5 Accelerator Operations 3. 6 Operational Radiation Safety 3. 7 Training and Qualification 3. 8 Program Review and Performance Evaluation 3. 9 Quality Assurance, Quality Control, and Configuration Control 3. 10 Document and Record Management 1. Covers most fixed, non-medical accelerators and encompassing almost all particles types and energies. 2. Covers all phases of accelerator facility from design to decommissioning (life-cycle approach). 3. Addresses both technical and managerial aspects of radiation safety program. 4. Sets both requirements and recommends for the protection of workers, public and environment. 5. Takes a graded approach for hazard control that is commensurate with risk. 6. Addresses engineered and/or interlocked safety systems that provide prompt radiation protection and safe accelerator operations.
