The National Academy of Engineering has launched a website, in cooperation with the Homeland Security department, which contains detailed fact sheets on four types of terrorist attacks.The fact sheets provide information on the science, engineering and health aspects related to biological, chemical, nuclear and radiological attacks, including historical perspectives and statistics on each.The sheets were assembled from a number of publications and the expertise of National Academies members, as well as input from experts in the various fields.The biological attack fact sheet contains information on the origin of such attacks, the difference between “infectious” and “contagious,” and how long it takes for symptoms to appear after exposure. The chemical attack sheet provides data on toxicity and how to react if a chemical attack is initiated.The nuclear attack sheet defines radioactive fallout and its dangers, the various short-term and long-term effects of exposure to radiation, and the likely scale of a nuclear terrorist attack. The radiological fact sheet explains what “dirty bombs” are, how they’re different from nuclear bombs, and the physical and mental effects of such attacks.Keep checking in at our CSO Security Feed page for updated news coverage.
