Radioactive Metals

The EJS Radioactive Decay Events Model simulates the decay of a radioactive sample using discrete random events. It displays the number of events (radioactive decays) as a function of time in a given time interval. You can change the initial number of nuclei, the decay constant and the time...

The Two State Nuclear Decay model simulates the radioactive decay of atomic nuclei into other nuclei. In this model, the resultant nuclei are stable and there are no intermediate decay states. Although the decay of a radioactive nucleus (radionuclide) is spontaneous and the time of its decay...
