It makes things luminescent because the nuclear war can block out the sun (called a "nuclear winter") so the living organisms have to start making their own light in order to survive. As for the 2-headed deer, I'm guessing the radiation can mutate the embryos inside the mother that later mutates the baby, like blending two twins together and the second twin's head sticks out of the other's.
