Every year, the NEOC carries out an aerial radiometry monitoring campaign. This involves aerial measurements of surface radioactivity. Under the intruction of the Swiss Nuclear Safety Inspectorate, the Swiss nuclear facilities are assessed every two years in turns. In addition to that, selected areas throughout Switzerland are measured too.
The aerial radiometry report is also published online (German and French). For further information on aerial radiometry, consult the homepage of the aerial radiometry expert group (FAR).
