Radioactive rabbit poo found at plutonium production site
A clean-up survey at the Hanford site in Washington State, where military-grade plutonium was produced during the early years of the cold war, discovered radioactive jackrabbit droppings around the site; the rabbits burrowed in the area and discovered the tanks in which nuclear waste is stored; they liked the salty taste of the radioactive cesium and strontium salts, so they began drinking and licking them routinely

Imagining new threats -- and countering them
DHS air transport security lab is in the business of imagining new threats — then developing the technologies to counter them; their dream? To build a “tunnel of truth” in each airport lined with hidden sensors, scanners, and rays; passengers would get zapped and sniffed as they passed, and would not need to take off their shoes, toss their liquids, or anything else
