Life average daily dose of radium-226 on some water samples collected at giri and kuje area of Abuja, North-Central Nigeria

226Ra concentrations were studied to represent the radiological risk of groundwater of the Giri and Kuje areas of Abuja, North-Central Nigeria. Two borehole water samples were collected from the Giri and Kuje areas of Abuja with a hand-dug well and Abuja Water Board as control. Inductively Coupled Plasma Mass Spectrometry (ICP-MS) was used to measure the concentrations of radionuclide of 226Ra exposed to the dwellers. The activity concentrations of 226R in groundwater supplies for drinking and domestic purposes ranges from 443
