The radenviro.ch website displays the daily averages of the measurements from all stations (01:00h – 01:00h). …….
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).

Tritium is a pure beta emitter of low energy. It is therefore not measurable by gamma spectrometry, the most widely used technique for monitoring radioactivity in the environment, and is therefore also ‘invisible’ to the URAnet aqua automatic river water radioactivity network.
