WASHINGTON (AP) — Air samples gathered last week contain radioactive materials that confirm that North Korea conducted an underground nuclear explosion, National Intelligence Director John Negroponte's office said Monday.
In a short statement posted on its website, Negroponte's office also confirmed that the size of the explosion was less than 1 kiloton, a comparatively small nuclear explosion. Each kiloton is equal to the force produced by 1,000 tons of TNT.
