Transitioning from High-Activity Radioactive Sources to Non-Radioisotopic (Alternative) Technologies: A Best Practices Guide for Federal Agencies [open pdf - 12MB]
From the Document: "Radioactive sources commonly used in medical, research, and industrial applications in the United States and elsewhere pose a security concern due to their potential for use in radiological dispersal devices (dirty bombs) or radiological exposure devices. The U.S. Government is considering how to reduce this security risk by adopting non-radioisotopic alternatives. Though existing radioactive technologies have a proven record of reliability and effectiveness, some non-radioisotopic alternatives that have emerged in recent decades demonstrate marked improvement in reliability, operability, viability, and availability. In certain cases, these alternatives offer a means for permanently reducing risk and cost by minimizing storage and final disposition charges. In accordance with its charter, the interagency Working Group on Alternatives to High=Activity Radioactive Sources (GARS) developed this guide to provide Federal departments and agencies with background information and recommendations on best practices for transitioning to non-radioisotopic technologies in cases where those technologies meet users' technical, operations, and cost requirements. The guide focuses on transitioning to non-radioisotopic technologies in medical applications, but many of these best practices could be broadly applicable to other uses of high-activity radioactive source."
