Things to Consider
Radiation threat, commonly referred to as a “dirty bomb” or “radiological dispersion device (RDD),” is the use of common explosives to spread radioactive materials over a targeted area. It is not a nuclear blast. The force of the explosion and radioactive contamination will be more localized.
While the blast will be immediately obvious, the presence of radiation will not be clearly defined until trained personnel with specialized equipment are on the scene. As with any radiation, you want to try to limit exposure. It is important to avoid breathing radiological dust that may be released in the air. Learn how to protect yourself during a radiation threat.
If There is a Radiation Threat or “Dirty Bomb”
And You Are Outside
And You Are Inside
If You have been Exposed to Radiation
Remember: To limit the amount of radiation you are exposed to, think about Shielding, Distance and Time.
As with any emergency, local authorities may not be able to immediately provide information on what is happening and what you should do. However, you should watch TV, listen to the radio, or check the Internet often for official news and information as it becomes available.
