\subsection{Calibration of Cesium-137 and Cobolt 60 Peaks}  The data that comes from the application UCS30 is intensity versus bins - the bins are just arbitrary values assigned when you start the program up. Having the spectrum in bins is not helpful because the bins can change from program to program, instead, we wanted to calibrate our spectrum into known energies. In order to calibrate our data for Cesium and Cobolt, we needed to know the known values for peaks in each spectrum. Cesium-137 has one peak at $661.6 \textrm{ keV}$ and Cobolt 60 has two peaks at $1.17 \textrm{ MeV}$ and $1.33 \textrm{ MeV}$. Values found from \href{https://www.cpp.edu/~pbsiegel/bio431/genergies.html}{Gamma Energy (KeV)}. In order to calibrate our spectrum and change the scale from bins into MeV, we defined the Cesium-137 peak and the two Colbolt 60 peaks which made a three-peak calibration. From there, the program was able to fill in the rest of the energies along the x-axis. Now, the program was completely calibrated for future trials. We did not alter any of the settings for the rest of the tests on gamma decay.
