Water is a universal solvent on earth and sources such as wells, rivers, springs, boreholes, and other freshwater bodies typically serve as a pathway for contaminants to enter the ecosystem while also supplying water for domestic and drinking purposes. The activity concentrations of radionuclides in borehole water in Igbajo town were assessed using gamma-ray spectroscopy, so as to effectively determine the degree of radiological risk to the environment and its inhabitants, the outcomes were used to calculate all the radiological impact parameters. The activity concentrations obtained for 40K, 238U and 232Thranged from 7.25±0.60 to 62.15±4.48Bq.L–1; 3.08±0.45 to 15.24±3.07 Bq.L–1and 1.08±1.10 to 17.75±1.59 Bq.L–1 and with average values of 23.12±1.59 Bq.L–1, 6.27±2.01 Bq.L–1 and 7.01±0.89 Bq.L–1 respectively. The Annual Effective Dose (AED) for ingested radionuclide in drinking water for an adult was1.4872 μSv.yr–1. The Radium Equivalent Activity Index, Raeq obtained was 34.9186 Bq.L–1. The estimated hazard indices Hint and Hext were 0.04876 and 0.06574 respectively. The Excess Lifetime Cancer Risk, ELCR (x10–6) was 5205.15. With a lifetime expectancy of 70 years, this high value suggests that there is a high chance of developing cancer.The value of the Annual Gonadal Equivalent Dose, AGED in the water was 55.9175μSv.yr–1. The estimated Gamma Index, Iγ was0.1273 mSv.yr–1. There is a significant health hazard to the environment and people living in the area owing to the radioactivity contents and radiological impact parameters. Hence, the need for urgent attention and means to prevent hazards which the overdose could cause.

The background radiation of Maryland School Complex was taken using RS-125 hand-held gamma spectrometer. The average concentration of the measured radionuclides were 19.16, 46.14, 165.00 Bq/kg for 238U, 232Thand 40K, respectively. The average value of measured dose rate and the estimated dose rate were 44.93 and 43.55Bq/kg. The mean values of the estimated radiological parameter were 53.45, 213.78μSv/y for indoor and outdoor annual effective dose. The excess lifetime cancer risk averaged 0.17, the hazard indices were 0.26 and 0.32 for external and internal respectively. The annual gonadal dose and radium equivalent were 303.90 μSv/y and 97.85 Bq/kg, while the gamma representative index was 0.69. The mean concentration of radionuclides measured and the estimated radiological parameter were within the recommended values. This therefore follows that the risk of exposure to ionizing radiation for both the staff and the students of the community is within acceptable limits.

“…Therefore monitoring and assessing groundwater quality based on radionuclides concentration is very important. However, many researchers within Nigeria have reported radionuclides and their health hazards in Air [6,7], building blocks [8], soil and water samples [1,[9][10][11] in mining fields [12,13], and in coaster sandy plain [14] etc., but very little information was reported about radionuclides in groundwater especially within the area. Therefore, the call for this research work in Kwara Polytechnic and its environs becomes necessary since most of the lands within the area were used as either dump-sites or farmland and an outbreak of water borne diseases as reported by some clinics within the area.…”

A NaI (TI) indicator was used to quantify the activity concentrations level of Uranium (U-238), Thorium (Th-232) & Potassium (K-40) in forty (40) groundwater samples collected across the premises of Kwara state polytechnic and its environs in order to determine the health hazard due intake of drinking water which has its origin from the subsurface. This investigation became necessary as a result of an outbreak of water borne diseases reported by the medical personnels in the clinics around the area. The results obtained from this measurement shows a range of values from 1.01 ± 0.02 to 8.21 ± 1.73, a mean of 3.88 ± 0.609 Bq.l−1 for U-238, 0.97 ± 0.01 to 14.81 ± 2.79, a mean value of 7.02 ± 0.99 Bq.l−1 Th-232 & 4.44 ± 0.12 to 147.33 ± 6.59 Bq.l−1, a mean of 48.08 ± 2.513 Bq.l−1 for K-40. The mean of these Radionuclides (U-238, Th-232 and K-40) are higher than the Universal value 10 Bq.l−1 for K-40 and 1 Bq.l−1 for U-238 and Th-232 as the permissible level for drinking water (United Nations Scientific Committee on Effects of Atomic radiation recommended (UNSCEAR)). In addition, most of the average values of the calculated radiological indices are within the recommended allowable tolerable boundary, although higher values were obtained in some within the study area. These results shows that U-238, Th-232 and K-40 concentrations and radiological parameters in the samples are high and low in values but might take a Probabilistic effect on the residents in the near future
