Lesson Title: Today we are learning about
What is nuclear radiation?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Some atomic nuclei are unstable.
  2. The nucleus gives out radiation as it changes to become more stable. This is a random process called radioactive decay.
  3. Activity is the rate at which a source of unstable nuclei decays.
  4. Activity is measured in becquerel (Bq)
  5. Count-rate is the number of decays recorded each second by a detector (eg Geiger-Muller tube).
  6. An alpha particle (α) is this consists of two neutrons and two protons, it is the same as a helium nucleus
  7. A beta particle (β) is a high speed electron ejected from the nucleus as a neutron turns into a proton
  8. A gamma ray (γ) is electromagnetic radiation from the nucleus
  9. The nuclear radiation emitted may be also be a neutron (n).
  10. Alpha is stopped by a few centimeters of air or a sheet of paper.
  11. Beta is stopped by a few millimeters of aluminium
  12. Gamma rays are stopped by a few centimeters of lead or a few meters of concrete.
  13. Gamma rays are the least ioninsing, because they are not charged.
  14. Alpha particles are the most ioninsing as they have a charge of plus 2.
  15. Students should be able to apply their knowledge to the uses of radiation and evaluate the best sources of radiation to use in a given situation.

Keywords:
  • Penetration: the extend to which radioactive wave or particle can pass through an object. (1)
  • Nuclei: the positively charged central core of an atom, consisting of protons and neutrons and containing nearly all its mass. (1)
  • Radioactive decay: the splitting of unstable nuclei to emit radioactive waves. (1)
  • Unstable: volatile and likely to react. (1)

AFL/Key Questions:
  1. What is meant by the term 'unstable' in terms of atomic nuclei?
    A nucleus that needs to emit subparticles to become stable.
  2. How can a nucleus become more stable in terms of radiation?
    Emit alpha, beta or gamma radiation.
  3. What is meant by the term 'activity' in terms of decay?
    The amount of radioactivity the radioactive isotope contains.
  4. What is radioactive activity measured in?
    Activity is measured in becquerel (Bq)
  5. What is the definition of 'count rate' and what piece of equipment can measure it?
    A Geiger-Muller tube can be used to measure count rate.
  6. What are the different types of nuclear radiation that can be emitted and what is each made up of?
    The nuclear radiation emitted may be: - an alpha particle (α) - this consists of two neutrons and two protons, it is the same as a helium nucleus - a beta particle (
  7. What is a beta particle (β)?
    A beta particle (β) is a high speed electron ejected from the nucleus as a neutron turns into a proton
  8. What is a gamma ray (γ)?
    A gamma ray (γ) is electromagnetic radiation from the nucleus
  9. What is released during nuclear fission?
    A neutron is emitted during nuclear radiation.
  10. What will stop the alpha radiation?
    Alpha is stopped by a few centimeters of air or a sheet of paper;
  11. What will stop the Beta radiation?
    Beta is stopped by a few millimeters of aluminium
  12. What will stop the Gamma radiation?
    Gamma rays are stopped by a few centimeters of lead or a few meters of concrete.
  13. Relative to alpha and beta, how ionising is gamma radiation?
    Gamma rays are the least ioninsing.
  14. Relative to beta and gamma, how ionising is alpha radiation?
    Alpha particles are the most ioninsing.
  15. What are the different uses of radiation?
    Radiation can be used in some of the following ways: *Thickness of paper. * Detecting leaks in pipes. * Cancer treatment. * Detection of disease.
