Abstract
Mineral and therapeutic waters widely occurring in the Polish Carpathians contain a vast amount of biogenic elements. However, radioactive elements like radium isotopes are also found in these waters. This paper presents the first results of the activity concentration measurements of 224Ra in selected mineral waters of the Polish Carpathians. Additionally, the content of 226Ra and 228Ra, and the activity ratios of 224Ra/228Ra, 224Ra/226Ra and 226Ra/228Ra in the waters were determined. The work was based on a method for the simultaneous determination of 224Ra, 226Ra and 228Ra in water samples using the a/b liquid scintillation spectrometer. The results show that the activity concentrations of 224Ra, 226Ra and 228Ra in the mineral waters are comparable and vary from ca. 220 mBq/L to above 1500 mBq/L. The activity ratios of 224Ra/228Ra, 224Ra/226Ra and 226Ra/228Ra are variable within the ranges of 0.68 to 1.48, 0.65 to 1.48, and 0.78 to 2.05, respectively. The committed effective dose resulting from the intake of 224Ra through the water consumption is far lower than that from 226Ra and 228Ra.
