Abstract:
Objective :To investigate the activity concentrations of natural radionuclides in drinking water (tap water andwell water) in urban and rural areas of Hohhot, assess the safety of drinking water, and to provide data support for localdrinking water radioactivity monitoring and management.
Methods :Representative samples of well water and tap waterwere collected from nine banners/counties/districts in Hohhot. Activity concentrations were measured using a low-back-ground gross α/β counter, an α spectrometer, inductively coupled plasma mass spectrometry, and a radium/radon analyzer.
Results :A total of nine tap water samples and nine well water samples were analyzed. For the tap water samples, gross αactivity concentrations ranged from 0.093 to 0.193 Bq/L, gross β from 0.091 to 0.225 Bq/L, uranium mass concentrationsfrom 2.32 to 10.36 μg/L, thorium mass concentrations from 0.09 to 0.20 μg/L,210Po activity concentrations from below theminimum detectable limit to 0.41 mBq/L, and 226Ra activity concentrations from 8.70 to 13.35 mBq/L. For the well watersamples, gross α activity concentrations ranged from 0.111 to 0.203 Bq/L, gross β from 0.111 to 0.270 Bq/L, uranium massconcentrations from 2.31 to 13.28 μg/L, thorium mass concentrations from 0.17 to 0.26 μg/L,210Po activity concentrationsfrom 1.03 to 2.12 mBq/L, and 226Ra activity concentrations from 15.38 to 23.63 mBq/L.
Conclusion :The activityconcen-trations of natural radionuclides in both well water and tap water in the Hohhot region were at environmental backgroundlevels and met national drinking water hygiene standards.
