isotope 1 decays to isotope 2, which decays to isotope 3, which decays to the stable isotope 4. The half-lives of the three decay processes are selected with the sliders.

continuous decay of 3 isotopes into a stable 4th isotope

id = continuous-isotope-production (do not remove this text)

Isotope 1 is continuously produced and it then undergoes radioactive decay. The decay products build up and, if radioactive, later decay with time. In this simulation isotope 1 decays to isotope 2, which decays to isotope 3, which decays to the stable isotope 4. The production rate of isotope 1 is fixed at 30 particles per minute. Isotope 2 is removed continuously at a rate selected by the slider.

Isotope 1 is continuously produced and it then undergoes radioactive decay. The decay products build up and, if radioactive, later decay with time. In this simulation isotope 1 decays to isotope 2, which decays to isotope 3, which decays to the stable isotope 4. The half-lives of the three decay processes are selected with the sliders. The production rate of isotope 1 is shut off after a time selected by a slider.

This simulation models a fission-type chain reaction in which a neutron strikes a nucleus of isotope A, splitting it into isotopes B and C and releasing X additional neutrons
