4. Description Abstract In this study, eighteen groundwater samples were collected from wells in villages around Zona, an area reported to host uranium mineralization and these were analyzed for mass/activity concentration of 226Ra, 228Ra and 232Th. Consumption of groundwater with elevated levels of 226Ra, 228Ra and 232Th may result to cancer, kidney and/or developmental defects in humans and other animals. The results obtained were compared for compliance with international guidelines for radionuclides in drinking water. Results of the study showed that activity concentration of 226Ra, 228Ra and mass concentration of 232Th ranged from 0.05 to 6.7pCi/L, 0.2 to 4.8pCi/L and 0.02 to 1.10µg/L, respectively. The higher levels of 226Ra in the studied samples compared with 228Ra in same sample might be as a result of 226Ra being part of 238U decay series as a results of which 226Ra is found over wide range of aquifer, it might also be an indication of secondary mineralization of uranium. Based on international guidelines regulating these radionuclides in groundwater, levels recorded at the time of the study fall within permissible limits of 20pCi/L for 226Ra and 228Ra while 232Th which is insoluble in water, therefore, has no regulated limit. All radionuclides analyzed fall within international guideline despite occurrence of uranium mineralization in the study area.
