Three-State Nuclear JS Model
written by Wolfgang Christian
The Three-State Nuclear Decay JavaScript Model extends the Two-State Nuclear Decay JavaScript Model to simulate the radioactive decay of atomic nuclei in which the parent nucleus first decays into an intermediate state before decaying into a stable state. Although the decay of both the parent and intermediate nucleus (radionuclides) is spontaneous and unpredictable, the probability of decay of each radionuclide is constant and is usually known. The model displays a color-coded sample with N1 parent nuclides, N2 intermediate state nuclides, and N3 stable state nuclides. Before the simulation starts, users can set the initial numbers N1 and N2, the decay constants k1 and k2, and the time interval between measurements Δt. The simulation counts the number of decay events ΔN1 and ΔN2 within Δt and stops when all nuclides are in the stable state.

The Two-State Nuclear Decay Javascript Model was developed using the Easy Java/JavaScript Simulations (EjsS) modeling tool. You can modify this simulation if you have Easy Java/JavaScript Simulations (EjsS) version 5.2 or above installed by downloading source code and importing the zip file into EjsS.

this is optimised layout for handphones use and slighs edits to the original, adding some half life visualise, circle dots instead of bar chart etc.
