An automatic wet deposition gamma analyser has been constructed. Precipitation is collected with a 1 m2 funnel and its 214Pb and 214Bi contents measured in a Marinelli beaker with an NaI(Tl) detector and a multichannel analyser. The amount of water in the beaker is measured with an ultrasonic sensor...
