A radiological dispersal device (RDD), often referred to as a "dirty bomb," combines conventional explosives with radioactive materials. Its primary purpose is to spread radioactive contamination over a wide area, potentially causing panic and disruption rather than mass casualties. RDDs are not nuclear weapons; they do not produce a nuclear explosion. Instead, they rely on the dispersal of radioactive substances, which can pose health risks depending on the type and amount of material used. Authorities, including emergency responders and public health officials, monitor and manage the risks associated with such devices to protect public safety.
