Book Nuclear missile tells how and why missiles shoot and explode. The fuel in the missile expands by centrifugal force generated in it by release of elastic convolutions in the fuel atoms. The energy generated on explosion is from centrifugal force in the matter. Proof for this is that energy can be released by physical force as in a fire cracker. The matter atoms have north south polarity as all matter like earth has that is why only a small current is generated when nuclear missiles explode There are no damaging radiations.
