President Obama praised the nations of Georgia and Moldova for breaking up black markets. He singled out Jordan for building a counter-smuggling team and the Ukraine and Mexico for ridding their territories of weapons grade uranium.

(President Obama) "We know that just the smallest amount of plutonium, about the size of an apple, could kill hundreds of thousands, and spark a global crisis."

But medical waste is also a threat. That's why he said in an agreement, announced today, between the U.S. and several European actors, will try to shift the treatment of cancer and heart disease away from medical isotopes that include uranium.
