Decommissioning Cost Estimate for the Ghana Research Reactor‐1 Facility Using the CERREX‐D2 Software

Science and Technology of Nuclear Installations, Volume 2026, Issue 1, 2026.
The Ghana Research Reactor‐1 facility would certainly be decommissioned, either at the end of its life or by a decision to discontinue its operation. In planning for GHARR‐1’s eventual decommissioning, estimating the overall decommissioning cost is a major activity that needs to be undertaken to support budgeting and decision‐making for the project. To

Lung counting with a highly segmented HPGe detector

Applied Radiation and Isotopes
A highly segmented High-Purity Germanium (HPGe) detector was used to measure 241Am activity located inside the lungs of an anthropomorphic phantom with various active and passive shield configurations. It was found that the background suppression shield does not play a significant role in reducing the Minimum Detectable Activity (MDA) after veto, based

Simulation of Structural Effects on Detection Efficiency in P-Type Coaxial High-Purity Germanium Detectors Using the Monte Carlo Method

Journal of Isotopes
Determining the full-energy peak efficiency (FEPE) of a high-purity germanium (HPGe) detector through experimental methods or Monte Carlo (MC) simulations is crucial for accurate radionuclide quantification. This study presents a meticulously constructed

Radiation protective qualities of some selected lead and bismuth salts in the wide gamma energy region

Nuclear Engineering and Technology, 2019
The lead element or its salts are good radiation shielding materials. However, their toxic effects are high. Due to less toxicity of bismuth salts, the radiation shielding properties of the bismuth salts have been investigated and compared to that of ...

GEANT4 models of HPGe detectors for radioassay

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2019
Radiation transport models of two high purity germanium detectors, GeII and GeIII, located at the University of Alabama have been created in GEANT4 \cite{geant4}. These detectors have been used extensively for radioassay measurements of materials used in various low background experiments.
