Exercise 4. Observe the establishment of the radioactive equilibrium in a decay chain. A) Enter the following values for the decay constants: 0.008 0.138 0.046 Run the simulation several times in “continuous mode” and observe how varies the amount of red and green nuclei at the end of the simulation. Which becomes more, which becomes less? B) Enter the following values for the decay constants (the red and the green decay constants are interchanged as compared to the previous exercise) : 0.008 0.046 0.138 How behaves the ratio of the green and the red nuclei at the end? Questions: a) What determines the formation rate of the daugthers? b) What determines the decay rate of the daugthers? c) How is the equilibrium between the formation and the decay is established?
