AbstractAbstract
[en] Design of large-volume (the sensitive volume is equal to 23l) gas proportional counter with internal filling is described. The multi-sectional counter structure and utilization of the mutual anticoincidence circuit make it possible to decrease the background noise up to 1-1,5 pulses per minute for 1l of volume at a normal pressure of a working gas and minimum external shielding. In this case high sensitivity of measurements (10-13 Ci/l of gas) is achieved. The counters with such sensitivity permit to determine nature tritium in surface waters and provide utilization of nature tritium as a tracer in oil fields
