Specification experiment — Learning outcome 4.6.8 – radioactive-source half-life
The A2 nuclear-decay learning outcomes require students to describe an experiment to measure the half-life of a radioactive source.

Measuring radioactive half-life
Measure the background count, then count a protactinium generator with a GM tube in ten-second windows and find the half-life from a graph of ln(corrected count rate) against time.
This simulation supports preparation and data-analysis practice. It does not replace carrying out real practical work.
