more than half the active nuclei decay The average life is the mean life time for a nuclei to decay. It is given as `tau = 1/lambda = T_"$\frac{1}{2}$"/0.693 Here, tau , lambda and T_"$\frac{1}{2}$"` are the average life, decay constant and half life-time of the active nuclei, respectively. The value of the average lifetime comes to be more than the average lifetime. Therefore, in one average life, more than half the active nuclei decay.
