Question: we are measuring the decay of 60co from a table...

Question details

We are measuring the decay of 60Co. From a table (table 7.2, Krane) for energy calibration standards: 60Co, t1/2= 5.27y, it produces two γ radiations, of energy 1173.238 keV and 1332.513 keV, respectively. In this problem we consider that we are only measuring the 1173.238 keV radiation.

(a) Calculate the energy of the Compton edge in a γ ray spectrum of this decay.

(b) Draw the energy spectrum (schematics), showing the photopeak and the Compton edge.

(c) Do we have also single and/or double escape peaks in this spectrum? If yes, then calculate and indicate in the graph.
