What are the goals of this site? 1. Provide guidance for health care providers, primarily physicians, about clinical diagnosis and treatment of radiation injury during radiological and nuclear emergencies. 2. Provide just-in-time, evidence-based, usable information with sufficient background and context to make complex issues understandable to those without formal radiation medicine expertise. 3. Provide web-based information that is also downloadable in advance, so that it would be available during an emergency if the internet is not accessible.
