Ionising radiation (ionizing radiation) is radiation that carries enough energy to free electrons from atoms or molecules, thereby ionizing them.
Best Answer: When electrons in an atom get excited, they jump to higher energy levels. In order for them to do this, they must absorb energy.However, when electrons calm down, they drop back down and thus release emit energy in the form of photons (the quanta of light).est Answer: When electrons in an atom get excited, they jump to higher energy levels.
