WebFig.6.2 shows a semi-logarithmic decay curve of a mixture of two activities that are completely independent, a composite decay curve. If the half-life values are sufficiently apart, it is seen to be possible to unravel the two separate decay curves, starting at the right-hand side of the curve, where the one activity has already disappeared. WebIn this problem, we are given that it takes 444 years for the substance to lose 1/2 of its radioactive nuclei, so in each year, it will tick through only one-444th of its half-life. So our exponent is t/444. We then can say that N (t) = N₀ (1/2) ^ (t/444) You asked what the constant value is for mercury 194.
