ENTRY C-04Dirty bomb: what it is and what to do
A dirty bomb is a regular explosion that spreads radioactive material around the area. The CDC says it cannot create an atomic blast, and the main danger is the explosion itself (CDC). If one goes off near you: get inside, stay inside, stay tuned.
What it is, in plain terms
The CDC describes a dirty bomb as a mix of regular explosives and radioactive material. When it goes off, the blast carries the radioactive material into the surrounding area. It is nothing like a nuclear bomb.
The CDC says the main danger is from the explosion, which can cause serious injuries and damage to people close by.
What to do if one goes off near you
- Get away from the blast area and get inside the nearest building. Cover your mouth and nose with a mask, cloth or towel until you are in (CDC).
- Take off your outer layer of clothing and bag it. The CDC says this can remove up to 90% of radioactive material.
- Wash with soap and water (see C-06).
- Stay inside and listen for instructions from officials.
- Get help for injuries. Call 911 for anyone hurt in the blast.
What KI will not do
Potassium iodide tablets will not protect you from a dirty bomb. The FDA says so directly. See C-03.
Common mistakes
- Panicking that it is a nuclear explosion. The CDC says it cannot create an atomic blast.
- Standing around to watch or film. Get inside.
- Keeping the same clothes on. Taking off the outer layer removes most of the material.
- Taking KI tablets. The FDA says they do not protect against a dirty bomb.
