WebIonising radiation. The radiation emitted from unstable nuclei is called ionising radiation because as it passes through matter it can dislodge outer electrons from atoms causing them to become ions.. Types of radioactive decay. An unstable nucleus can decay by emitting an alpha particle, a beta particle, or a gamma ray.

WebDecay is random: We cannot predict when an individual atom will emit (produce) ionising radiation. An unstable nucleus can become more stable over time by randomly (spontaneously) emitting ionising radiation. This process is called radioactive decay. Substances that decay radioactively are “radioactive substances”. Four Types of … WebMar 19, 2024 · A complete and ready to deliver high quality GCSE lesson from Barclayfox. There is nothing to do !
