to check, use the fact that
The decay constant is the fraction of the number of atoms that decay in 1 second. It is the constant λ in the decay equation: dN/dt = -λN The - sign indicates decay, dN/dt is the number of decays per second (also known as 'Activity') and N is the number of atoms present.
assuming N = 1600, λ or k = 1, or p = 0.1000,
the following screenshots suggests both simulation are consistent!
