Ionising radiations

Ionising radiation includes both electromagnetic radiation; such as x-rays and gamma radiation and particle radiation, such as alpha, beta and neutron radiation. Its main feature is that it has enough energy to ionise atoms and molecules, ie, to generate positively and negatively charged particles from electrically neutral atoms and molecules. When going through matter, eg, through a cell or an organism, ionising radiation gives off energy.
