What is the primary function of a dirty bomb?

The primary function of a dirty bomb is to disperse radioactive material over an area. A dirty bomb, technically known as a radiological dispersal device (RDD), combines conventional explosives like dynamite with radioactive materials. Unlike a nuclear bomb, which undergoes a nuclear reaction and causes massive destruction, a dirty bomb's primary aim is to spread radioactive contamination, instilling fear and chaos within a population.

Such devices are designed to contaminate the environment and should provoke concern over long-term health effects, rather than causing immediate, large-scale destruction. This tactic seeks to cause panic and disrupt normal activities rather than to create a significant physical explosion or protect against nuclear threats, making it essential for public safety telecommunicators to recognize the true nature of this type of threat.
