New automatic network for measuring radioactivity in the air in Switzerland

14 September 201811 November 2022 André Gurtner

The new automatic network for monitoring airborne radioactivity operated by the Federal Office of Public Health (FOPH) is operational. It replaces the old network, which was put in place after the Chernobyl accident and became obsolete. This network makes it possible to identify and quantify radionuclides in the air and to generate an alarm if set thresholds are exceeded.

Origin of tritium in the environment

5 February 201618 November 2022 André Gurtner

Tritium is the radioactive isotope of the element hydrogen. Its half-life is 12.3 years. As tritium is an isotope of hydrogen, its behaviour in the environment is mainly related to the water cycle (tritiated water; tritium replacing hydrogen in the water molecule).

In situ gamma spectrometry

25 April 201618 November 2022 André Gurtner

In situ measurements are mainly carried out in the vicinity of nuclear power plants and research centers (PSI and CERN), as well as in monitoring persistent cesium-137 contamination from atmospheric nuclear tests and the Chernobyl accident.

Low-level measurements of artificial radionuclides in the Aare and Rhine

22 January 201618 November 2022 André Gurtner

The introduction of artificial radionuclides into river water can occur either through direct discharge of liquid radioactive substances through sewage pipes or through precipitation (leaching from atmospheric discharges).
