The United States Nuclear Arsenal in Miniature
This field full of ceramic cones represents, in miniature, the 25 000 warheads of the american nuclear arsenal. Plutonium is the principal nuclear explosive in most of these warheads. One of the greatest risks in using plutonium as a civilian nuclear fuel is the relative ease with which some of it could be stolen. Plutonium can be used — by anyone who gets their hands on it — to make nuclear weapons.
