Automation of the γ-ray spectrometry setup of the Environmental Radioactive Laboratory at NRF-iThemba LABS
Environmental γ-ray spectrometry plays a critical role in radioactivity monitoring, radiation protection, and nuclear safety assessments. Conventional spectrometric analysis relies heavily on manual peak identification and expert interpretation, which can be time-consuming and subjective, …

An evaluation of the natural radioactivity in the soils of Okahandja and Karibib, Namibia
The natural radioactivity and associated hazards in the soils of the towns of Karibib and Okahandja have been studied by gamma spectroscopy. Each town was divided into ten geographical areas and five soil samples were collected across each area. These samples were processed and placed in …

Efficiency calibration of a gamma-ray detector for measuring environmental radiation
The Environmental Radioactivity Laboratory (ERL) of iThemba LABS conducts research into levels of natural and anthropogenic radioactivity in the environment. The laboratory-based measurements are conducted using a low-background Hyper Pure Germanium (HPGe) detector system. A critical aspect of such …
