‘New START’ ratified, but loose nuclear material remains worrisome

Yesterday we discussed which nuclear weapons will be affected by the New START agreement, which was ratified by the Senate. Today we examine another worrisome type of nuclear material ? the unaccounted-for kind, which terrorists have the best chance of acquiring.

Hans Blix, who served as director general of the International Atomic Energy Agency (IAEA) from 1981 to 1997, helps us find out where these other unsecured nuclear material is located around the world, and what can be done to solve this problem.
