    Abstract: In this study, a fluorescent compound; N, N'-Bis (2-Hydroxy Benzylidene) Benzidine, (C26H20N2O2) prepared and calculated by FT-IR, 1H NMR, UV-Vis and fluorescence procedures. The 1H NMR field examined in Chloroform-d solvent. The Fourier Transform-Infrared FT-IR in hard case detected in the area 4000-600 cm-1. The absorption spectrum of the Bis (2-... Show More

    Abstract: A total of 25 well water samples from various locations of Idah and environs including Ofukolo, Ega, Ede - Adejo, and Ede - Alaba, have been investigated for their 222Rn concentrations using liquid scintillation counter manufactured by Packard Instrument Company. The concentration of 222Rn in the well water samples was found to vary in the range 3.... Show More
