    What is ionising radiation?

    A bit of GCSE science revision: Elements can exist in different forms, known as isotopes. Different isotopes of an element have the same number of protons in the nuclei of their atoms, but different numbers of neutrons. Some isotopes have unstable nuclei, because they have the wrong balance between protons and neutrons. These isotopes are radioactive.The emission of radiation eventually makes the nucleus stable again -so that it is no longer radioactive.
