Definition

1. Noun:
   • A type of explosive device: A "dirty bomb" is a conventional explosive that has been combined with radioactive material. Its primary purpose is not a massive nuclear explosion but to disperse radioactive contamination over a wide area.
   • A radiological dispersal device (RDD): This is the technical term for a "dirty bomb." It uses explosives to scatter radioactive dust and debris, creating a zone of contamination and causing fear and disruption.

Usage

• The term "dirty bomb" is used to describe a specific and concerning type of weapon that combines conventional terrorism with radiological hazards.
• It is primarily discussed in contexts of security, counter-terrorism, emergency response, and public safety.

Examples

• Noun:
  • Security forces conducted drills to prepare for a potential dirty bomb attack.
  • The report analyzed the psychological and economic impact of a dirty bomb detonation in a major city.
  • Authorities seized materials that could be used to construct a dirty bomb.

Advanced Usage

• "dirty bomb threat": A warning or indication that such a device may be used.

  • The city was on high alert following a dirty bomb threat.

• "dirty bomb scenario": A hypothetical situation or planning exercise involving the use of such a weapon.

  • Emergency responders trained for a worst-case dirty bomb scenario.

Variants and Related Words

• Radiological dispersal device (RDD): The formal, technical term for a dirty bomb.
• Radiological weapon: A broader category that includes dirty bombs and other devices designed to spread radioactive material.

Synonyms

• Radiological bomb: A less common synonym emphasizing the radioactive component.
• RDD: The acronym for the technical term.

Important Notes

• A "dirty bomb" is not a nuclear weapon (like an "atom bomb" or "nuclear bomb"). It does not create a nuclear fission or fusion explosion. The reference definition calling it an "atom bomb" is technically inaccurate; it is a radiological, not a nuclear, device.
• The primary effects are contamination, fear, and economic disruption, rather than the massive blast and heat of a nuclear explosion.

Noun

1. an atom bomb that leaves considerable radioactive contamination
