Ionising radiation (ionizing radiation) is radiation that carries enough energy to free electrons from atoms or molecules, thereby ionizing them.
Lead does not block gamma radiation. Ionizing radiation, is literally a photon cannon that just spits out ions that just hits the molecules, and changes its structure NOT Atomic structure. Like DNA for example, can be completely destroyed or altered.
