FRONTLINE'S INVESTIGATION: Three of the most alarming incidents of nuclear material diversion - in Prague, Munich, and Landshut (1994) - are linked to the same Russian middleman.
This color-coded map on nuclear proliferation lays out: the declared nuclear weapon states; the undeclared states; the states with active/suspected nuclear weapons programs; and those states which have renounced such activites or, have abstained from developing weapons programs.
Across Russia there are over100 sites with known nuclear material (amounting in total to an estimated 1000+ metric tons of highly enriched uranium and over100 metric tons of bomb grade plutonium). This map shows some of these locations, and gives details on the kind of nuclear material and its safety status.
