Jude Okemsinachi Anaegbu, Agomuo John Chidowerem, Ige Olumide Oluwasanmi — International Journal of Research and Innovation in Applied Science · The rapid industrialization of Kaduna Metropolis has raised significant environmental concerns regarding the release of Naturally Occurring Radioactive Materials (NORMs) into surrounding ecosystems. This study assesses the radiological impact of industrial activities at the Sincer Development Company, an iron and metal scrap processing facility located behind the Flour Mill in Kudende, Kaduna. Soil samples were collected from ten active industrial points and one control site, and analyzed using Thallium-activated Sodium Iodide [NaI(Tl)] Gamma Spectrometry to quantify the activity concentrations of ²²⁶Ra, ²³²Th, and ⁴⁰K. The results revealed significant variability in activity concentrations across the study area. The ²³²Th activity concentrations ranged from 25.70 to 89.74 Bq/kg with a mean value of 61.43 Bq/kg, while the control site exhibite
