Efficiency calibration of BEGe and extended range detectors

Applied Radiation and Isotopes, 2014
Any approach to efficiency calibration of HPGe detectors sensitive to low-energy gamma-rays and X-rays has to deal with true coincidence summing. We developed a method based on the integration of the EFFTRAN code into the commercial Genie2K™ gamma-ray spectrometry software. EFFTRAN's role is to compute true coincidence summing corrections and to obtain

Efficiency calibration of airborne γ-ray spectrometer using sourceless efficiency calibration method

Journal of Radioanalytical and Nuclear Chemistry, 2019
Based on the exponential law of narrow beam γ ray and calculus principle, a numerical calculation model for sourceless efficiency calibration of airborne γ-ray spectrometer has been developed. Through experiments and simulations, it was found that the relative deviation between the efficiency of airborne γ-ray spectrometer with different surface ...
