This video explores the concept of radioactive decay from Theme E of the IB Physics SL & HL courses. Firstly, nuclide notation is explained and the nature of radioactive decay is discussed. Examples of alpha decay, beta-minus decay, beta-plus decay and gamma decay are explored. This is followed up by a discussion of half-life and activity using decay curves, including how to account for background radiation in experimental data.
