The measurements support the installation of modern water purification systems, especially to lower natural radionuclides. A liquid scintillation spectrometer and an HPG \u03b3-spectrometer were used to measure activity concentrations of <sup>222<\/sup>Rn, total uranium, <sup>226<\/sup>Ra, and <sup>228<\/sup>Ra isotopes. LSC-based methods were employed to measure <sup>222<\/sup>Rn and <sup>226<\/sup>Ra in a two-phase sample; uranium was extracted using a 20% solution of TBP in o-xylene to determine activity concentration via LSC. Recently developed simple procedures have been used to concentrate water radioactivity with ion-exchange resins, thereby improving detection limits for uranium and radium isotopes. These methods rely on straightforward techniques and widely available materials. Water radionuclide data collected over the past three years include <sup>228<\/sup>Ra. We compared it with data from the previous three-year set of similar water sample studies and with data from studies conducted on drinking water sources in the Zhytomyr region from 1999 to 2019. The data were consistent across sources. The <sup>226<\/sup>Ra\/<sup>228<\/sup>Ra ratio mainly ranges from 0.5 to 3.5. Radiation doses were expressed as lifetime average annual doses, considering age-dependent dose coefficients and relevant weighting factors. When evaluating potential radiation exposure, emphasis is placed on Ra isotopes, as they contribute most to the radiation dose. The activity concentration of <sup>228<\/sup>Ra ranged from 3 to 500 mBq\/L, corresponding to an irradiation dose of 2.7 to 452 \u00b5Sv\/y, which accounts for up to 96.2% (median \u2013 65.6%) of the total irradiation dose from U and Ra isotopes ingested through drinking water.<\/p>\n\n\n\n<p><strong>Cite this article :<\/strong> Buzynnyi, M., Prihod\u2019ko, R. &amp; Mykhailova, L.
