Abstract Objective To evaluate the effects on human health of carbon-14 in drinking water by determining it and estimating the in-take dose.Methods Inorganic radiocarbon concentration in some tap-water and well water samples from Fujian and Hainan province were determined. A simple inorganic radiocarbon measurement procedure was employed, using the bubbling and direct absorption method, followed by low-level liquid scintillation spectrometry.Results The results of sixteen samples showed there was difference in tap-water from different district, and there was difference between tap-water and well waer. The effective dose caused by drinking well water was different from tap-water.Conclusion The effective dose caused by drinking water which was about 10-9 Sv/a, impact on health can be ignored.
