“…The effective radium content ranges from 0.574 Bqkg -1 -1.170 Bqkg -1 while the radon mass exhalation rate ranges from 0.104 Bqkg -1 d -1 -0.212 Bqkg -1 d -1 . The radon mass exhalation rate obtained in our study is comparable with the reported values for some building materials in Zaria, Nigeria (Asuku et al, 2017;Arabi et al, 2015). The alpha index ranges from 0.00287 -0.00585.…”

In this study 10 soil and 11 ground water samples were randomly collected, and the 222Rn concentrations were measured using a DURRIDGE RAD7 electronic radon detector. The radon concentration in ground water ranged from 0.53 BqL-1 to 5.13 BqL-1 with a mean value 2.37 BqL-1. The results show that all the groundwater samples collected have 222Rn concentrations below the US EPA Maximum Contaminant Level (MCL) of 11.1 BqL–1 (for states without radon monitoring policy and enhanced indoor air programs). All the ground water samples also have 222Rn concentrations below MCL of 100 BqL–1 recommended by EU. The annual effective dose due to ingestion (Hing) of 222Rn in the groundwater ranged from 0.00386 – 0.03744 mSvyear-1 with a mean value of 0.01706 mSvyear-1. These values are within the ICRP recommended reference level of 1 mSvy–1 for the intake of the radionuclide in water by the general public for a prolonged exposure. The effective radium content, radon mass exhalation rate and alpha index of the soil samples varied from 0.574 – 1.170 Bqkg-1, 0.104 Bqkg-1d-1 – 0,212 Bqkg-1d-1 and 0.00287 – 0.00585 respectively. The alpha index suggests that none of the selected soil samples have a radon mass exhalation that could cause indoor radon concentrations exceeding 200 Bqkg-1. Therefore, it is concluded that the radon concentration in ground water and soil in the study area indicate that the ground water is safe for drinking and it is safe to use the soil as a building material.

“…Globally, elevation of activity concentrations of radionuclide and its radiological consequences from buildings as well as building materials from geological origin have been reported by many researchers, among are: Lu et al [ 10 ], Arabi et al [ 11 ], Ge and Zhang [ 12 ], and Isinkaye et al [ 13 ]. Recently, activity assessment and radiological risks associated with tiles made in Nigeria have been reported by Joel et al [ 14 ] and Joel et al [ 15 ].…”
