Simulating radioactive decay. Small cubes used to simulate the random action of radioactive decay. Each block represents a nucleus of a radioactive material. Each has one black side. The blocks are thrown and any that land with the black side face up represent decayed nuclei. These are removed and the rest are thrown again. This is repeated at regular intervals. The half life is deemed to be the number of throws needed for the number of dice to reach half the number at the beginning. The results are recorded on the chart at lower right and can be plotted on a graph.
