Attention MIT physics department!
Please alert your colleague in the linguistics department, Noam Chomsky, that there’s a big difference between a radiological (“dirty”) bomb and a nuclear bomb. In spite of his earlier forays into homeland security punditry, he evidently doesn’t know the difference, and conflates the two here:
Take, say, nuclear terror. The American intelligence systems estimate that the likelihood of a “dirty bomb,” a dirty nuclear bomb attack in the United States in the next ten years, is about 50 percent. Well, that’s pretty high. Are they doing anything about it? Yeah. They’re increasing the threat, by increasing nuclear proliferation, by compelling potential adversaries to take very dangerous measures to try to counter rising American threats.
Repeat after me:
dirty bomb = traditional explosives laced with radiological material, but no nuclear reaction.
nuclear bomb = nuclear reaction
