This analysis was done by weighting the histogram by the mass of the sample. The window is [1356,1368] and was expanded by one channel on each side to find the error in the counts.

Below is a plot of the activity as a function of time
This gives the constant of 14.5046 +/- 0.00345043. Now find the initial activity
Since the plot is made with reference to the mixture's measurement time (first point plotted 108 minutes after the mix was measured) means that the constant should be the activity at the time the mixture was being measured.
