On the specification
| Board | Spec | Statement |
|---|---|---|
| AQA GCSE 8463 | 4.4.2.1 | Radioactive decay and nuclear radiation |
| Edexcel GCSE 1PH0 | 6.23 | Describe how the activity of a radioactive source decreases over a period of time |
| Edexcel GCSE 1PH0 | 6.24 | Recall that the unit of activity of a radioactive isotope is the Becquerel, Bq |
| Edexcel GCSE 1PH0 | 6.25 | Explain that the half-life of a radioactive isotope is the time taken for half the undecayed nuclei to decay or the activity of a source to decay by half |
| Edexcel GCSE 1PH0 | 6.26 | Explain that it cannot be predicted when a particular nucleus will decay but half-life enables the activity of a very large number of nuclei to be predicted during the decay process |
| Edexcel GCSE 1PH0 | 6.27 | Use the concept of half-life to carry out simple calculations on the decay of a radioactive isotope, including graphical representations |
| OCR GCSE J249 | P6.1d | Recall that some nuclei are unstable and may emit alpha particles, beta particles, or neutrons, and electromagnetic radiation as gamma rays |
| OCR GCSE J249 | P6.1l | Recall the differences in the penetration properties of alpha particles, beta particles and gamma rays |
For teachers
This GCSE Physics lesson teaches radioactive decay is random: activity and count-rate. It suits Foundation and Higher tier students.
