Sound traveling very fast is so convenient
In the first scene of "Fallout" John and Helen are having a conversation in a room. Suddenly a nuclear detonation is seen through the window. An uproar is heard at the same time of the initial flash, then we hear a big thunder. Even if we consider the first noise as being not the direct noise from the explosion but some local secondary effect of the radiation wave (which travels at the speed of light), the main thunder comes 6 seconds after the flash, therefore the detonation is about 2 Km (1.24 miles) away: they would have been killed almost instantly. Given the apparent distance of the mushroom, the thunder would have been delayed by 60 seconds.
