Radon Monitors Jungfraujoch & Uni Bern

Since December 2009 two identical radon (222Rn) monitors, built at ANSTO, are working in parallel at Bern and on Jungfraujoch. The instruments operate on a two-filter dual-loop principle (Whittlestone and Zahorowski, 1998), where the signal is directly proportional to gaseous 222Rn.

At Bern, air is sampled at the Physics Institute, on the flat rooftop of a four storey building (7° 26’ 19” E, 46° 57’ 5” N, sampling height 575 m a.s.l.), which is located on the edge of a bluff, about 20 m above the historical part of the city.

At Jungfraujoch (7° 59’ 2” E, 46° 32' 53" N), air is aspired from outside the research station at 3454 m a.s.l.

Horizontal distance between both stations is 60 km.

Data is uploaded on the day of measurement at midnight (CET). Note: This data is automatically analysed. Instrumental failures or environmental disturbances to measurements can go unnoticed. For quality controlled data, please contact Franz Conen.
