I'm trying to find the branching ratio for Na-22. For that, I need to calibrate my detector sensitivity for different evergy levels. For that, I measured Eu-152 gamma spectrum, and now I wish to reference it to known values. I've been desperately Googling any query I can think of to find the required data, but I didn't find anything.

The radionuclides investigated have a relatively challenging decay scheme and their spectra are known to suffer from losses due to summation (gamma-gamma, gamma-X and P. De Felice ±Uncertainty in gamma spectrometry N.12/78 Total count rate Methods for determination: o Sum of counts in the whole pulse-height spectrum, with linear extrapolation to zero count rate o Integral counting above an energy threshold Total count rate: well-defined quantity (for a given threshold) corresponding to the energy of incident gamma-rays of a single energy. This is desired for gamma-ray spectroscopy because we are interested in knowing the energies of the various gamma-rays that are emitted by a source.
