A dirty bomb, or radiological dispersion device (RDD), is a bomb that combines conventional explosives with radioactive materials in the form of powder or pellets. The purpose is to blast radioactive material into the area around the explosion, causing radiation exposure and long-term contamination of buildings.The latest US National Intelligence Estimate reports that “Al Qaeda is probably still pursuing chemical, biological or nuclear weapons and would use them if its operatives developed sufficient capability”.
Response measures to a suspected RDD attack include: leaving the immediate area but avoiding public transport so not to spread radiation; getting inside a building away from blast dust; removing clothes and placing in a sealed plastic bag; taking a shower as soon as possible.
