Radioactive equilibrium<br \/>\nis investigated experimentally by having students measure the activity of 214 Bi from two different<br \/>\nsamples, obtained using different preparation procedures from an uraniferous rock. Students are<br \/>\nguided in understanding the mathematical structure of radioactive equilibrium through a modelling<br \/>\nactivity in two parts. Before the lab measurements, a dice game, which extends the traditional<br \/>\n\u2018radioactive dice\u2019 activity to the case of a chain of two decaying nuclides, is performed by<br \/>\nstudents divided into small groups. At the end of the laboratory work, students design and run a<br \/>\nsimple spreadsheet simulation modelling the same basic radioactive chain with user defined decay<br \/>\nconstants.
