| Popis: | This study assessed the influence of geological depth and formation on activity concentrations of 232Th, 226Ra and 40K in soil and groundwater, and radio-chemical health risks. Preference ranking organisation method for enrichment evaluation and geometrical analysis for interactive aid indicated significant correlation between 232Th and 40K, thus indicating potential similar primordial origin. Deepest depth rocks at 145 m and 148 m constituted of dark coloured silicified schist exhibited minimal activity with potential hydro-geological interactions with groundwater. Age-dependent annual effective ingestion dose for 226Ra and 232Th are higher than the UNSCEAR reference dose, thus the groundwater is unsuitable for long-term consumption. |
