Explore the structure of the atom and the nature of radioactivity. Study the history of atomic models, types of radioactive decay, half-life, and the uses and hazards of nuclear radiation.
• Describe the nuclear model of the atom (protons, neutrons, electrons) and its historical development. • Explain isotopes and the random nature of radioactive decay. • Identify alpha, beta, and gamma radiation. • Define and use the concept of half-life.
• Compare the hazards of contamination and irradiation. • Discuss the medical uses of radiation for imaging and therapy. • Assess the risks of ionising radiation to human tissue.
• Explain nuclear fission and chain reactions. • Explain nuclear fusion. • Compare nuclear fuel energy density to chemical fuels.
