New York City\'s new 16-page anti-terrorist preparedness manual, produced by a consortium of 20 government agencies and released in July, contains such advice as: If you encounter radiation, go outside (if you\'re inside a building) or go inside (if you\'re outside a building); Do not accept packages from strangers; If you find yourself holding a mysterious substance, put it down. Also offered is the familiar advice from a generation ago: If you can\'t get out of a building, \"(Duck) under a sturdy table or desk.\" [Reuters, 7-11-03]
