Specified practical work — Specified practical work – half-life of a model radioactive source

WJEC specifies determination of the half-life of a model radioactive source, for example using dice; this is a non-ionising simulation of random decay.

Half-life of a model radioactive source

Throw 120 dice fifteen times, removing the sixes as decays, then plot the number remaining against throw number and read two half-lives from the curve.

This simulation supports preparation and data-analysis practice. It does not replace carrying out real practical work.
