ABSTRACT: The elemental composition of Fenugreek (Trigonella foenum-graecum) seed powder was quantitatively analyzed using Energy Dispersive X-ray Fluorescence (EDXRF) spectroscopy with a Rigaku NEX CG system. The study aimed to evaluate essential and trace elements relevant to nutritional and pharmacological applications. Measurements were performed under optimized conditions using Mo, Cu, RX9, and Si secondary targets in a helium.....

ABSTRACT: Naturally occurring radionuclides such as 40K, 226Ra and 232Th are present in soils and sediments, with concentrations influenced by geology and human activities. Scrap metals, which may contain orphan radioactive sources, and flood events, which redistribute contaminated sediments, represent potential environmental pathways of exposure. This study evaluates the concentrations of 40K, 226Ra and 232Th in soils from scrap yards and flood-affected areas in Maiduguri, Nigeria, to determine associated radiological risks to the public. A total of 32 soil samples were collected and analyzed using NaI(Tl) gamma spectrometry. Activity concentrations were quantified, and radiological.....
