Abstract: Efficiency calibration by standard materials of known activity is usual protocol for γ-ray spectrometry. In general, 40K activity is measured from proper efficiency calibration covering broad energy range within which the 1460.83 keV photopeak falls. However,… read more here.

Abstract: In this paper, a new efficiency calibration scheme is proposed for the inhomogeneous adsorption column, in which the segment efficiencies modeled by the Monte Carlo toolkit Geant4 are weighted according to the fraction distributions of… read more here.
