  1. Alpha beta and gamma

  2. What is radioactive decay?

  3. What is alpha (α) radiation? 2 neutrons, 2 protons Description Note:– An alpha particle is the same as a helium nucleus +2 Electric charge 4 Relative atomic mass Stopped by paper or a few centimetres of air Penetrating power Strongly ionizing Ionizing effect Effect of magnetic/ electric field Weakly deflected

  4. What is beta (β) radiation? High energy electron Description -1 Electric charge 1/1860 Relative atomic mass Stopped by a few millimetres of aluminium Penetrating power Weakly ionizing Ionizing effect Effect of magnetic/ electric field Strongly deflected

  5. Gamma () radiation High energy electromagnetic radiation Description 0 Electric charge 0 Relative atomic mass Stopped by several centimetres of lead or several metres of concrete Penetrating power Very weakly ionizing Ionizing effect Effect of magnetic/ electric field Not deflected

  6. Types of radiation and penetrating power
