Gamma-ray spectroscopy (2.19)

Student's Manual In this experiment, we will analyse energy spectrums of Cobalt-60 and background radiation and calculate the mass absorption coefficient for lead. Also the different ways in which gamma ray photons interact will be studied.
Sample Results A calibrated Cobalt-60 spectrum for a voltage of 800 V and for a coarse gain value of 4.
A calibrated energy spectrum of background radiation taken at 750 V and a coarse gain value of 8 built over a time interval of around 80 hrs.
Mass absorption coefficient is the p1 parameter in this case.The graph is of ln(I/I_o) vs thickness using Co-60 peak with E=1.33 MeV.
