Radioaktiver Zerfall

The program ZERFALL simulates the decay of the atoms of a radioactive substance. The set of undecayed atoms is first shown as a black block, a decayed atom is drawn in white. The "selection" of the just decayed atom is done randomly, if the atom has already decayed at the selected location, a new one is selected, and so on. The number of decayed atoms in a time unit is drawn as an activity curve.
