Nine underground water springs from the Szczawno-Jedlina health resort and one from Zagorze Śląskie were investigated for natural radioactivity content (²²²Rn, ²²⁶,²²⁸Ra, ²³⁸,²³⁴U). In order to obtain the necessary data, two different nuclear spectrometry techniques were applied: a liquid scintillation counter that enabled us to determine ²²²Rn and ²²⁶,²²⁸Ra isotope content, and α spectrometer for measurements of uranium isotopes (²³⁴,²³⁸U) in investigated samples. The activity concentrations of ²²²Rn in investigated samples varied from 6 Bq/l to 227 Bq/l. For radium isotopes the concentrations ranged from 13 mBq/l to 808 mBq/l for ²²⁶Ra and from below 30 mBq/l to 184 mBq/l for ²²⁸Ra. The activity concentrations for uranium isotopes varied from 2.4 mBq/l to 964 mBq/l for ²³⁴U, and from 1.0 mBq/l to 725 mBq/l for ²³⁸U. The isotopic ratios between uranium and radium isotopes (²²⁶Ra/²²⁸Ra, ²²⁶Ra/²³⁸U, ²³⁴U/²³⁸U) and annual effective doses due to these isotopes’ consumption were evaluated. Risk levels due to carcinogenic effects of ²²⁶,²²⁸Ra and ²³⁴,²³⁸U radionuclides consumed with water were estimated.
