Abstract

More than three quarters of the dose from ionizing radiation is caused by natural radiation sources. In most European countries, groundwater is used as a source of drinking water, what can be an additional source of radiation since naturally occurring radionuclides in the bedrock can dissolve into groundwater. Although the Directive 2013/51/EURATOM establishes several parametric and screening values for different radioactivity parameters, there is a lack of harmonized information and publications available that evaluate the overall condition of drinking water in EU. Thereby, it is challenging to uniformly assess the current situation in European countries in regards of effective doses caused by the consumption of drinking water. This paper aims to collect the available information on the main radionuclides of interest in drinking waters of different European countries and create an overview of the existing situation.

摘要

超过四分之三的电离辐射剂量是由天然辐射源引起的。在大多数欧洲国家，地下水被用作饮用水源，这可能是额外的辐射源，因为基岩中天然存在的放射性核素可以溶解到地下水中。尽管指令 2013/51/EURATOM 为不同的放射性参数建立了多个参数和筛选值，但缺乏可用于评估欧盟饮用水整体状况的统一信息和出版物。因此，就饮用水消耗引起的有效剂量而言，统一评估欧洲国家的现状具有挑战性。
