A typical gamma ray spectrum is shown in figure 3. The number of counts is plotted as a function of channel number for the radioactive isotope 22 Na. There are a few features to notice from this spectrum. 1. 22 Na emits gamma rays of two distinct energies. These appear as lines having some width and are marked along with their energies in the

The machine can be calibrated to relate peak energies to gamma ray energies, and as We placed Cobalt 60 and Sodium 22 in front of the detector, in order to Gamma Constant: 14.9 mR/hr 38.2 mrad/hr (gamma dose) Detection information: Usable Detectors listed with estimate efficiencies.
