That is my understanding: yes, it would be safe to eat those apples. Also, yes, it would be perfectly safe to eat apples that were exposed to x-rays for one year. X-rays are not powerful enough to split atoms, so if the apple started out by not having unstable (i.e. radioactive) atoms, it will end up the same. Some molecules in the apple will split, but not the atoms themselves.
The story would be different if you exposed the apple to neutron bombardment. During a nuclear explosion, a lot of neutrons are released, but the intensity of the neutron bombardment decreases with the square of the radius, so if you are far enough for the apples to not be physically destroyed, they'll most likely be safe to eat.
