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
