Dirty Bomb does an excellent job of illustrating how the public would panic if a Dirty Bomb was detonated, but does a poor job on the technical side by overstating the dangers of the radioactive substances released by such a device. The writer has a poor handle on the measurement of radioactivity, and adds to the scare by being non descript as to the substances used. I was disappointed with the portrayal of emergency services and how the leaders where willing to pull back crews so quickly after the event, I feel they would actually be much more heroic as a whole, and not as scared as they where portrayed. Relistically speaking, Hiroshima and Nagasaki were subject to the release of a lot more radioactive substances and radiation than any dirty bomb would ever release, and they where rebuilt within a few years, and people live there today. Despite the technical inaccuracy, The movie does illustrate terrorists greatest tool, the ability to instill a sense of panic in the public.
