The simulation shows the temporal development of a decay chain – consisting of 5 members –, where the 5th member is a stable isotope (its decay constant is zero), and the decay constants of the first four elements can be set. The screen refreshes in every second. In the initial state there are 2482 atoms from the first element. The 5 elements of the decay chain are represented by circles of different colors: red =>blue=>green=>brown=>purple.  More...
