https://journals.fukashere.edu.ng/index.php/jjsr <p>Jewel Journal of Scientific Research a journal published by Federal University of Kashere publishes original research papers, review articles, short communications, book reviews, forum articles, announcements or letters. JJSR intends to provide a biannual medium for the communication of research findings in agriculture, sciences and science education. It would be published in June and December each year. Researchers from all countries are invited to publish their findings in agriculture, biology, chemistry, computer, ecology, environment, mathematics, physics, agroinformatics, respective education papers or multidisciplinary research of interest on its pages. There is no bias with regard to taxon or geographical area. Manuscripts should present new findings that have not been published before and are not submitted for publication elsewhere. Papers must be in English. All manuscripts are peer reviewed by at least two independent referees. Papers accepted for publication by the editorial board are subject to editorial revision.</p> Faculty of Science, Federal University of Kashere, Gombe State en-US Jewel Journal of Scientific Research 2384-6267 https://journals.fukashere.edu.ng/index.php/jjsr/article/view/929 <p>Artisanal and small-scale mining activities often pose environmental and health risks to surrounding ecosystems. This study evaluates radiological hazards and potential exposure levels in soils from active and abandoned mining sites in Iwere-Ile, Oyo State, Nigeria. Twenty-two soil samples were analyzed using a Gamma-ray Spectrometer with a NaI(Tl) detector to determine the activity concentrations of naturally occurring radionuclides. The mean specific activities of ⁴⁰K and ²³²Th contributed about 15% and 9%, respectively, to the total radioactivity. The absorbed dose rate from terrestrial gamma radiation ranged from 5.86 to 217.48 nGy h⁻¹, averaging 58.06 nGy h⁻¹, slightly above the UNSCEAR global reference value of 55 nGy h⁻¹. The annual effective dose equivalent (AEDE) varied between 0.02 and 0.76 mSv yr⁻¹, remaining below the 1 mSv yr⁻¹ public dose limit. Although the annual gonadal dose equivalent (AGDE) exceeded international recommendations, the internal and external hazard indices were both less than unity, indicating minimal radiological threat. Overall, agricultural activities in the area can be considered radiologically safe despite ongoing mining operations.</p> T. J. Aluko P. O. Olagbaju F.E.
