Detailed MCNP Simulations of Gamma-Ray Spectroscopy Measurements With Calibration Blocks for Uranium Mining Applications

AREVA Mines and the Nuclear Measurement Laboratory of CEA Cadarache are collaborating to improve the sensitivity and precision of uranium concentration evaluation by means of gamma-ray measurements. This paper reports gamma-ray spectra, recorded with two high-purity germanium detectors, on standard cement blocks with increasing uranium content, and the corresponding MCNP simulations. The detailed ...
