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 **    • KS3 Biology      • KS3 Chemistry      • KS3 Physics      • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #GCSE #Physics #study #revision #school #exam #AQA #OCR #Edexcel
