In order to determine the age of two Cesium-137 samples, we kept the same settings used from our calibration results and did one sample at a time. Both were placed on the slot second from the top in the scintillator. Sample one started out with $5 \mu \textrm{Curies}$ and had a published date. We were able to find out that sample one is 211 months (17.583 years) old because we know the half life of Cesium-137 is 30.2 years. Both samples were measured for the same amount of time. After taking the spectrum data for both samples, it was clear that one spectra was younger because the whole spectra had higher intensity values than than the older sample. This happens because the younger sample has more radioactive material to create gamma rays. Figure \ref{fig:Sample_Two_Peak} \ref{fig:Sample_one_Peak}  shows the younger sample in blue (much higher intensity) and Figure \ref{fig:Sample_one_Peak} \ref{fig:Sample_Two_Peak}  the older sample in orange. From this graph, it is clear that the samples are very different in age.
