Committee chairman Ole Danbolt Mjøs announced the winner of the 10 million Swedish crown (USD 1.29 million) prize at the Nobel Institute in Oslo at 11 a.m.

The prize was awarded in two parts, to the International Atomic Energy Agency (IAEA) and its director-general Mohamed ElBaradei.

Last minute speculation had centered on the award going to anti-nuclear efforts. The year 2005 marks the 60th anniversary of the bombings of Hiroshima and Nagasaki in Japan and commentators noted the committee's habit of awarding anti-nuclear activists at ten-year intervals.

In 1995, British ban-the-bomb scientist Joseph Rotblat won with his Pugwash organisation. In 1985, the award went to a US-Soviet group of doctors, International Physicians for the Prevention of Nuclear War.
