英文摘要 | This research was focused on the analyses of the hydrochemical behaviour of long-lived natural radionuclides (Po-210, (210)ph , U-234,U-238, Th-230,Th-228, Ra-226,Ra-228) in groundwaters from Spanish aquifers with different geological characteristics and the evaluation of the dose by ingestion of these waters. The study was performed by the gross alpha-beta, alpha spectrometry and physicochemical analysis of a set of bottled drinking waters. Radionuclide activities in the investigated aquifers were highly variable. High concentration of Pb-210 is associated with granitic bedrock and reducing conditions. On the other hand, the highest( 238,234)U concentrations were found in carbonate aquifers. Activities of Ra-226 are largely controlled by ion exchange reactions due to the presence of relatively high concentration of chloride. Several waters exceeded the parametric value for gross alpha mainly due to U-234, Ra-226 and/or Pb-210 concentrations. Moreover, the content of 226 Ra and 210 Pb in the water contributed mainly to the indicative dose. |
