How was ducking and covering supposed to save a person from a nuclear blast:)? - nuclear metal core scooter wheels

I saw scenes of the Cold War era gave films that would have given him advice on how to survive a nuclear holocaust. Are, in one scene, students turn in their desks as they would during an earthquake. Excuse me, but I think it is a big difference between the destruction caused by the earthquake and performed by an atomic bomb! Finally, atomic bombs have been known to vaporize metal, so as to escape and one person can meet to save a nuclear explosion?:)
