Radon in Drinking Water

Radon can dissolve in underground water. As soon as the water reaches the surface, the dissolved radon escapes and can cause dangerous concentration peaks in the air. In practice, this primarily poses a health risk to the waterworks workforce. In certain situations, residential buildings can also be contaminated.

The Swiss Federal Ordinance for Drinking Water specifies a maximum guideline value of 100 Bq/l for radon in drinking water. However, critical radon concentrations in the air can occur at much lower concentrations of radon in drinking water.

Radon is transported to the surface by water (Source: SVGW, slightly adapted by SUVA).

How high is the radon concentration when the drinking water is fed into the network or arrives at the consumer? We can find out for you.

What should be done if the radon concentration in the drinking water is too high? – Often, different supply lines to a reservoir carry water with different concentrations. The inlets are measured individually and under varying meteorological conditions.
