P15 syllabus statements

  1. 1. 02/06/14 P15 Radioactivity Syllabus statements
  2. 2. 15.1 Detection of radioactivity 1. Demonstrate understanding of background radiation. 2. Describe the detection of α-particles, βparticles and γ-rays. (β+ are not included; β-particles will be taken to refer to β–)
  3. 3. 15.2 Characteristics of the three kinds of emission 1. State that radioactive emissions occur randomly over space and time. 2. Recall for radioactive emissions, and use to identify them: • their nature • their relative ionising effects • their relative penetrating abilities.
  4. 4. 15.2 Characteristics of the three kinds of emission 3. Describe the deflection of α-particles, βparticles and γ-rays in electric fields and magnetic fields. 4. Interpret their relative ionising effects.
  5. 5. 15.3 Radioactive decay 1. State the meaning of radioactive decay. 2. Use equations (involving words or symbols) to represent changes in the composition of the nucleus when particles are emitted.
  6. 6. 15.4 Half-life 1. Use the term half-life in simple calculations, including the use of information in tables or decay curves.
  7. 7. 15.5 Safety precautions 1. Describe the hazards of ionising radiation to living things. 2. Describe how radioactive materials are handled, used and stored in a safe way to minimise the effects of these hazards.
  8. 8. 15.6 The nuclear atom – Isotopes 1. Use the term isotope. 2. Give and explain examples of practical applications of isotopes.
