Exposure to heavy metals and natural radionuclides through various means can dispose mankind to deterioration of health. It is essential and of great importance to monitor environmental radiation level and understand the consequences of radiation exposure for ecological conservation and human health. Aero-radiometric data collected from Nigeria Geological Survey Agency (NGSA) for selected...
A mobile radiation detection unit (MRDU) featuring a 2”x2” LaBr3:Ce detector was developed for real-time radiation monitoring in terrestrial environments. The detector underwent calibration for energy, resolution, and efficiency using standard point sources at iThemba LABS and standard calibration pads at NECSA. Subsequent environmental measurements were conducted at two distinct sites: The...
Mining exploration usually involves drilling and sometimes excavations to visually the core. The study assessed whether excavations at the A-Cap Uranium mine lease area had the potential to cause a rise in background levels within the mining site. The Inspector 1000 digital multichannel handheld survey meter and the Mobile Radiation Detection Unit - a LaBr3(Ce) detector in a backpack geometry,...
Studying the structure of the nucleus at the frontiers of nuclear stability presents a number of difficult challenges. The advent of radioactive ion-beam facilities has required a step change in the sensitivity of the nuclear instrumentation required to study the expected new and exciting nuclear phenomena. The detection of gamma radiation is at the heart of nuclear structure physics...
The Portable African Neutron-Gamma Laboratory for Innovative Nuclear Science (PANGoLINS) project aims to further investigate measurements of neutrons which forms an important component part on site or in transit and the detection of both fissile material for the use in decarbonised energy sources or disposal thereof. iThemba LABS has pioneered a mobile gamma-ray detection unit which allows a...
The growing industrial hub of Matsapha, Eswatini, presents a double-edged sword. While it fuels economic progress, concerns loom regarding its impact on the precious natural water resources. This study delves into the environmental consequences of industrialization on the water quality of Matsapha’s rivers and streams. Utilizing the Water Quality Index (WQI) as a comprehensive assessment tool,...
The detection of odours emitted by meat products when they start to spoil remains a challenge. In response to this, materials of ZnO decorated with palladium nanoparticle was synthesised using the hydrothermal method for the purpose of testing its gas sensing properties. After the synthesis of these nanoparticles, various characterization techniques for the investigation of both physical and...
