"It's not highly enriched uranium. It could have come from so many different ways," ElBaradei told reporters in Dubai. "That's why we're looking at so many different scenarios."
Uranium can be found naturally in low concentrations and must be enriched before it can be used in either power plants or nuclear weapons. Highly enriched uranium is the type used in atomic bombs..." "It could have come in peoples' clothes, for example. It could have come through some nuclear material stored somewhere. It could have come, as Syria says, through the bombings."
