The Centers for Disease Control and Prevention (CDC) has published An Introductory Guide to the CDC Radiation Hazard Scale, a new resource to help public health professionals, emergency preparedness planners, emergency responders, and health communicators use the CDC Radiation Hazard Scale before and during radiation emergencies.
This guide describes how the scale was developed, explains the five color-coded hazard categories, provides guidance for assigning hazard levels, and includes examples of applying the scale during radiological and nuclear incidents. The scale can help people better understand the level of radiation hazard in their immediate surroundings.
