From neutrino to wine…
To minimize the intrinsic radioctivity of the detector, all materials have been selected using germanium photon detectors of very low level natural radioactivity

Activity Activity 137137Cs (mBq/l)Cs (mBq/l)
With such detectors : measurement of 137Cs in wine
Activity 137Cs year

Bourgogne 1934
Presence of 137Cs in the Bourgogne bottle ! Not 1934 but later then 1950 (activity ~100 mBq/l)
