Radioactive isotopes in Danish drinking water


In samples of drinking water representing more than 40 % of the water delivered from water works in Denmark. The levels for beta radioactivity were met in the all waterworks while total alpha radioactivity exceeded the screening levels for 13 water suppliers. The radiation dose is far below the limit for radioactivity set in the Drinking Water Directive 98/83/EC. Groundwater from very different types of geological structures also shows that the concentrations of radioactivity were sufficiently low to meet the requirements in the Drinking Water Directive. The risk of finding drinking water in Denmark with unacceptable concentrations of radioactivity is very small.
