Description
In this work the utilization of nuclear hydrological instruments using Liquid Scintillation Counter (LSC) and laser absorption spectrometer (Cavity Ring-Down Spectrometer, CRDS) were employed. All samples from the precipitation were treated for isotopic instruments. Tritium values were analyzed with electrolytic enrichment and LSC while deuterium and oxygen-18 were calculated on CDRS. As a result, tritium values ranged 0.6-13.3 TU (tritium unit), deuterium values are between -76.44 and -7.5 ‰ (per mil) and oxygen-18 values show -10.67 to -2.42 ‰. The data of tritium and stable isotope can be used to input data for studying the dynamics of groundwater in Ongkharak area.
