Definition & Operational Usage
A radiological dispersal device (RDD), commonly known as a 'dirty bomb,' integrates conventional explosives with radioactive materials to disseminate radioactive contamination over a wide area. The primary objective of an RDD is to induce panic and disrupt societal functions rather than to inflict mass casualties through explosive force. Not to be confused with a nuclear bomb, which relies on nuclear fission for immediate destruction, an RDD's impact is primarily psychological and environmental. Effective incident management frameworks, such as the Incident Command System (ICS), are crucial for addressing the challenges posed by RDD events.
