The URA group collaborates with the cantons in order to monitor the radioactivity in foodstuffs.
Samples of foodstuff are taken every year according to the sampling plan of the FOPH or during campaigns organized by the cantons. The monitoring programme includes measurements (gamma spectrometry, strontium-90, tritium) of staple foods such as milk, wheat and vegetables taken in the vicinity of nuclear power plants and industries using tritium, but also from other locations in Switzerland.
In addition, other foodstuffs such as mushrooms, meat, fish, fruits, spices etc. from Switzerland or imported from other countries are also analysed by the cantonal laboratories.
Results for samples of milk and cereal are published on radenviro.ch. Information on other foodstuffs can be found in the annual report “Environmental radioactivity and radiation doses in Switzerland” (Chapter 5).
