The Survival Guide: What to Do in a Biological, Chemical, or Nuclear Emergency. By Angelo Acquista. Random House, 288 pp., $12.95.

As I write this review, the possibility of a chemical or biological attack on U.S.  forces in Iraq is very much on the minds of both military leaders and American citizens. The possibility of such an attack occurring on U.S. soil is also a matter of concern for many. How prepared are we for such an act of aggression, and what should we do were it to happen?

Angelo Acquista, cited as the "pro bono medical director of the New York City Mayor's Office of Emergency Management," addresses precisely these concerns. (His survival guide has its own Web site at www.911guide.com.)
