Exposure human to high doses of radon-222 through ingestion in water or inhalation as gas can lead to stomach or lung cancer. In this research, the concentrations of Radon-222 (222Rn) were investigated from eleven (11) water samples collected at different locations within Geidam town, Geidam Local Government Area of Yobe state, using liquid vacuum degasification process and RD-35 device. From the results obtained, the minimum value of radon concentration is found in the main borehole of Low-Cost near Friday mosques to be 0.57 pCi/L, while the maximum value measured which was related to a water tank in the general hospital quarters recoded 1.89 pCi/L. The overall average radon concentration for all water samples is found to be (0.99 ± 0.14) pCi/L. According to the achieved results, the radon concentration from all the water samples was lower than the maximum allowable concentration set by EPA and WHO guidelines.
