Equations (simplified for quick and dirty use!!!)

  2 * (E keV)^2
___________________ = Compton Edge
  511 keV + 2(E keV)

                  2 * (E keV)^2
E keV – ________________ = Back Scatter peak
                  511 keV + 2(E keV)

(Tom’s opinion)
Best source for calibration: Cs137
Best detecttor type: NaI(Tl) 1″ or greater!
Best free MCA software: PRA 8
