This procedure is simply the relating of the channel
position of the peak in a gamma spectrum to the energy of the gammaray.
 Assume a linear relationship between the gamma energy and channel
number, y = mx + c
 Choose a radionuclide that gives two well spaced peaks or a mixture
of nuclides for energy calibration processes
 Place the source to give a few thousand cps and collect for ~2000 s
 Using the MCA cursor, make a note of the channel number
corresponding to the maximum of each peak
 Solve the two simultaneous equations to find the slope and intercept


If a peak was found at channel number 403, what energy would it be in the
spectrum?
