Economic Consequences of a Radiological or Nuclear Attack

Property destruction, loss of life, and injuries sustained from a nuclear or radiological attack have significant economic consequences. The loss of productive assets can extend for long periods and generate significant economic loss. Economic impacts caused by an event need to be addressed in sequential order beginning with the detonation, atmospheric dispersion, and deposition of the fallout from the weapon. Report by Pacific National Northwest Laboratory.
