GCSE Physics - Alpha, Beta & Gamma Radiation | How Ionising & Penetrating They Are (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ *** WHAT'S COVERED *** 1. Isotopes and Radioactive Decay * An explanation of stable and unstable isotopes. * How unstable isotopes undergo radioactive decay to become more stable. 2. The Four Types of Nuclear Radiation * A breakdown of the properties of the four main types of nuclear radiation. 3. Alpha (α) Radiation * Its composition (a helium nucleus), charge, ionising power and penetrating power. 4. Beta (β) Radiation * Its composition (a high-speed electron), charge, ionising power and penetrating power. * An explanation of how beta particles are formed from neutron decay. 5. Gamma (γ) Radiation * Its nature as an electromagnetic wave, ionising power and penetrating power. 6. Neutron Radiation * The process of a neutron being emitted from an unstable nucleus. 7. Summary of Penetrating Power * A comparison of what is required to stop alpha, beta, and gamma radiation. *** CHAPTERS *** 0:00 Introduction to Isotopes & Radioactive Decay 1:08 What is Alpha Radiation? 2:09 What is Beta Radiation? 2:55 What is Gamma Radiation? 3:39 What is Neutron Radiation? 4:00 Summary of Radiation Penetrating Power *** PLAYLISTS *** https://youtube.com/playlist?list=PLidqqIGKox7VzYfPIVt8T09xOLNcolCe4&si=8JmDajxjtba6rdc3 https://youtube.com/playlist?list=PLidqqIGKox7UZ3mWhbHv2aA_1vnbsfRPq&si=q3hEKdA4v7kbfwMe https://www.youtube.com/playlist?list=PLidqqIGKox7UTimdJ3eFcnt6xL9GUt2a6 https://youtube.com/playlist?list=PLidqqIGKox7XPh1QacLRiKto_UlnRIEVh&si=orIUwL3o2jOoiYjT https://youtube.com/playlist?list=PLidqqIGKox7X5UFT-expKIuR-i-BN3Q1g&si=DcihOwUkd9oWbbdp https://youtube.com/playlist?list=PLidqqIGKox7WeOKVGHxcd69kKqtwrKl8W&si=Y8MsO-FK948jnxpS https://youtube.com/playlist?list=PLidqqIGKox7UVC-8WC9djoeBzwxPeXph7&si=-7i5Iq7yOeJrhtu6 https://youtube.com/playlist?list=PLidqqIGKox7VKJD2WxRhoKaI6JGLVean8&si=NH_Q1ujhVgACM2FU #GCSE #Physics #study #revision #school #exam #AQA #OCR #Edexcel
