Radiological hazards assessment of laterite mining field in Ilorin, North-central Nigeria

Untitled

“…This may be as a result of the abundant nature in this region of the country as was recently discovered. This is in agreement the work of [18,19,21] where the mean uranium content reported was higher than the world average value in soil. But this is contrary to [22] who recorded a lower value and this may be attributed to the differences in location where the samples were collected or compared with other studies was believed to be because these radiation elements are not evenly spread in the earth crust [4] .…”

Soil-to-plant transfer of 40K, 238U and 232Th and radiological risk assessment of selected mining sites in Nigeria

“…Moro with a landmass of 3272 km 2 has a total population of 108,792 people (City population, 2016). Kwara state has an elevation of 251 m (823 feet) with a humid wet-dry climate and an average yearly rainfall of 1,200 mm ( Orosun et al., 2020b ). The yearly average temperature of Kwara is 26.2 °C, with peak temperature of around 30 °C during the hottest month, March.…”

“…The portable gamma spectrometer has a wide-ranging energy of 30–3000 keV capable of detecting radiation of terrestrial origin. More information about RS125 gamma spectrometer can found in previous studies where the instrument was used ( Orosun et al., 2020b , 2020c ; Adagunodo et al., 2018 ). Measured values available in our article data ( Orosun et al., 2020c ).…”

“…Mining of tin, gold, beryllium, coal and other minerals has been associated with enhancement of naturally occurring radioactive materials in the environment because it involves the extraction of huge volumes of subsurface earths that usually contains varying levels of the naturally occurring radionuclides ( Orosun et al., 2019 ). The health and ecological impacts of mining and dumping of the resulting tailings have been investigated by several scientists in Nigeria ( Orosun et al., 2020a ; Orosun et al., 2020b ; Orosun et al., 2021 ; Orosun et al., 2022a ; Adesiji and Ademola, 2019 ; Usikalu et al., 2019 ; Usikalu et al., 2022 ; Aliyu et al., 2015 ; Arogunjo et al., 2009 ; Ibeanu, 2002 ). The researchers measure the activity concentrations of the primordial radioelements in the mined mineral soils to evaluate the human health and environmental risks of the mining activities.…”

Radiotoxicity risk assessments of ceramic tiles used in Nigeria: The Monte Carlo approach

“…Building and construction materials such as tiles, granites, quartz, marble resulting from mineral rocks generally contain varying quantities of contaminants such as heavy metals (PTEs) and naturally occurring radionuclides like 238 U, 232 Th, their products, and the non-series 40 K (Omeje et al, 2018;Joel et al, 2018a,b,c;Orosun et al, 2020a;Orosun et al, 2020b, Orosun et al, 2021a. These toxic metals and the primordial radionuclides are typically inherited from the mother rock (such as granitic rocks) during the pedogenic process (Orosun et al, 2020a) .…”
