About

This updated guide describes how first responders and local agencies should act in the first hours after a radiological dispersal device (RDD) explosion. It explains steps like checking for radiation, warning the public to stay inside, starting rescue operations, measuring radiation levels, and planning safe evacuations. It gives advice on protective equipment and clear messages for the public. The guide uses a 100-minute timeline but says each community can adjust it as needed to keep people safe during an RDD emergency.
