A hybrid sourceless efficiency calibration method for detecting nonuniform and irregular radioactive sources

The data set is mainly the Monte Carlo simulation data and the hybrid sourceless efficiency calibration method calculation data, and through the processing of the experimental data to get the relevant result analysis diagram. It mainly includes relative error of the geometric efficiency between the cylindrical detector and the equivalent spherical detector for gamma rays at 609 keV, relative error of the geometric efficiency between the cuboid detector and the equivalent spherical detector for gamma rays at 609 keV, relative errors in the full energy peak efficiency of the cuboid detector for the small cells between the Monte Carlo simulation and the analytical calculation, relative errors in the full energy peak efficiency of the cylindrical detector for the small cells between the Monte Carlo simulation and the analytical calculation, the full energy peak efficiency of the validation experiment.
