El-Baradei, who shared the award with the International Atomic Energy Agency (IAEA) he heads, told an audience at Uppsala University in Sweden that the world faced "a fundamental choice."
He predicted that "in the next 10-20 years, 20 or 30 countries will have nuclear weapons” if the world continues to rely on atomic weapons.
The alternative, he said, is for all countries to end their nuclear weapons programs and to destroy their existing nuclear arsenals.
El-Baradei said that accepting a world with nuclear weapons "is the beginning of the end" for mankind.
