Half-life and nuclear decay


  • This simple simulation by Andrew Duffy at BU illustrates several different sample decay curves. Students can watch an array of 400 nuclei “decay” over time and a plot of the number of remaining nuclei is produced.


These PhET simulations can reproduce Alpha and Beta decay

  • Alpha Decay


  • Beta Decay


  •  JavaLab offers this simulation of the mathematics of half-life, with an array of tokens that can be animated in steps, one half-life at a time, and graph the number remaining.
