Because they turn one kind of atom into a completely different kind of atom (and give off, or accept energy).
In normal chemical reactions, the individuals atoms are not changed, just rearranged.

radioactive changes are changes within the atom, reducing/changing the element to smaller element. Chemical changes are those that change the arrangements of of different elements with out changing the atoms they are comprised of. ie fire to gas; cooking food to make it turn to carbon, separating sodium from chloride in salt, etc. Radioactive changes are changes speific to the element itself.

It is because the radioactive materials decay over time, losing mass and energy.

Because they are on the nuclear (atomic) rather than the chemical (molecular) level!
