A Radiological Dispersal Device (RDD) is a conventional explosion used to spread radioactive material. What is another name for it?

A Radiological Dispersal Device (RDD) is indeed commonly referred to as a "dirty bomb." This term accurately reflects the device's function of spreading radioactive material using a conventional explosive to contaminate a wide area. The primary intent behind a dirty bomb is not to cause widespread destruction through a nuclear explosion, but rather to create panic and fear, contaminate the environment, and complicate emergency response efforts.

The use of the term "dirty" distinguishes it from other types of bombs that may involve nuclear reactions, such as a nuclear bomb or fusion device. A dirty bomb primarily highlights its radiological impact without the overwhelming explosive power associated with true nuclear weapons. Understanding this terminology is crucial for emergency responders, as it shapes how they approach incidents involving radiological materials and informs their response strategies.
