PITTSBURGHIn the current Fox television adventure series, "24," a terrorist explodes a small nuclear bomb in Los Angeles. In the May 2007 issue of the journal Health Physics, Carnegie Mellon researchers Keith Florig and Baruch Fischhoff offer simple, practical advice that ordinary citizens can use when faced by such threats.
Specifically, the two scientists address the following questions: whether it is worth citizens' time to stock supplies needed for a home shelter, how urgently should one seek shelter following a nearby nuclear detonation, and how long should survivors remain in a shelter after the radioactive dust settles.
Carnegie Mellon's Florig, a senior research engineer and Fischhoff, a university professor, report that many families simply can't afford the government stocking guidelines; they need help to protect themselves.
"A number of emergency-management organizations recommend that people stock their homes with a couple dozen categories of emergency supplies," said Florig of Carnegie Mellon's engineering and public policy department. "We calculated that it would cost about $240 per year for a typical family to maintain such a stock, including the value of storage space and the time needed to tend to it."
Their research also suggests that many families who could afford to follow the stocking guidelines might think twice about whether the investment was really worth it, given the low probability that stocked supplies would actually be used in a nuclear emergency.
"Government websites such as Ready.gov recommend that people take shelter or evacuate following a nuclear blast, but provide no information that might help people determine how much time they have to react before a fallout cloud arrives," said Florig. We advocate a more nuanced message with simple rules for minimizing risk based on how far p
