If the event horizon of a Black Hole is the point at which nothing can return, If a nuclear bomb is detonated 5 meters within the event horizon, would a person 5 meters outside the event horizon be unharmed?

The bomb is detonated 5 meters within the event horizon, and the person is 5 meters outside the event horizon.  Would he be unharmed even though he was only 10 meters from the explosion? 
(and assuming he can keep himself from passing into the event horizon)

Yes. All of the radiation and hot material from the explosion *must* fall inwards. No light, sounds, or anything will go "upwards" and escape the black hole. There would be no way to tell whether a bomb had gone off or not.
