The University of Liverpool Nuclear Physics research group has been involved in studying the structure of the nucleus at the frontiers of nuclear stability since its inception. To compliment these studies, and to push the boundaries of our knowledge we have been forefront at designing...
Gamma-ray spectrometer with a single HPGe or NaI:Tl detector shielded with lead is often used to measure the activity concentration of radionuclides in soil samples. A passive water shield to reduce background radiation reaching the detectors was designed using GEANT4 Monte Carlo simulations and then constructed. IAEA-375 soil and beach sand each placed in Marinelli beaker were measured for 48...
Naturally occurring radionuclides of terrestrial origin exists in every component of the earth. Making humankind to be continuously exposed to ionizing radiation, which is dangerous to human health. Monitoring of environmental radioactivity is very crucial to minimizing exposure above the threshold limit. Consequently, the background radioactivity due to 232Th, 238U, and 40K for some locations...
A mobile radiation detection unit (MRDU) was developed to measure the radiation levels outside the iThemba LABS buildings, within the borders of the facility. The main attraction of this mobile unit is the fact that it is equipped with a LaBr3:Ce detector. This detector is superior to more conventional detectors (such as NaI:Tl) because of typically better spectral resolution, a high photon...
In this work, a HPGe detector in a low-background setup was used to determine the activity concentrations of 238U, 232Th and 40K in soil samples collected in and around some gold mining areas of the Mayo-Kebbi region in Chad. Subsequently, the radiological risks due to these natural radionuclides were also assessed. The range of activity concentrations of 238U, 232Th and 40K varied...
The present work aimed at establishing the extent and distribution of the activity concentration levels of 238U daughter-nuclides; 226Ra and 222Rn in the
West Rand-area of Johannesburg. The main motive was to ascertain whether
the exposure of the nearby residents to ionising radiation due to former mining
activities was within the maximum acceptable limit of 1.0 mSv/y for the public....
Implementation of the k0-standardization method of Neutron Activation Analysis (NAA) technique and k0-IAEA program with the Nigeria Research Reactor-1 (NIRR-1) laboratories’ irradiation and counting facilities was carried out as part of a series of projects aimed at achieving one of the goals of the Strategic Utilization Plan for NIRR-1. Adoption of the k0-standardization method of NAA...
Everyone on the planet is exposed to some background radiation. Human exposure to ionising radiation is one of the scientific subjects that attract public attention, since radiation of natural origin is responsible for most of the total radiation exposure of the human exposure.
This study presents the results of Gamma-ray spectroscopy and its associated radiological risk of beach sand and...
Environmental pollution is attributed mainly to poor management of municipal solid waste and chemical disposal. Of great concern are heavy metals which emanate from both natural and anthropogenic processes, and these end up in soil, water, air and the interfaces thereof. Heavy metals are very toxic even at low concentrations, and they can bio-accumulate to toxic levels when frequently...
This review gives insights into the levels of naturally occurring radionuclides (NOR), radioactive particles of air dust, heavy metals, environmental pollution and related hazards at Agbara industrial Estate, Agbara, Ogun State, Nigeria. Due to many industries located in Agbara industrial estates, there is much discharge of gaseous effluent, waste disposal. Industrial air dust harbours several...
