This research was focused on the analyses of the hydrochemical behaviour of long-lived natural radionuclides (²¹⁰Po, ²¹⁰Pb, ^234,238U, ^230,232Th, ^226,228Ra) 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 ²¹⁰Pb is associated with granitic bedrock and reducing conditions. On the other hand, the highest ^238,234U concentrations were found in carbonate aquifers. Activities of ²²⁶Ra 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 ²³⁴U, ²²⁶Ra and/or ²¹⁰Pb concentrations. Moreover, the content of ²²⁶Ra and ²¹⁰Pb in the water contributed mainly to the indicative dose.

这项研究的重点是分析西班牙不同含水层地下水中长寿命天然放射性核素（²¹⁰ Po，²¹⁰ Pb，^234,238 U，^230,232 Th，^226,228 Ra）的水化学行为，并通过摄入评估剂量这些水。这项研究是通过瓶装饮用水的总α-β，α光谱和理化分析进行的。被调查含水层中的放射性核素活动变化很大。²¹⁰ Pb的高浓度与花岗岩基岩和还原条件有关。另一方面，最高的^238,234在碳酸盐含水层中发现了U浓度。的活动²²⁶ Ra的主要由离子交换反应，由于氯的浓度较高的情况下进行控制。几个水主要由于²³⁴ U，²²⁶ Ra和/或²¹⁰ Pb的浓度而超过了总α的参数值。而且，水中²²⁶ Ra和²¹⁰ Pb的含量主要是指示剂量。
