A carbon dioxide-proportional counting system is described. The preparation and purification of CO/sub 2/ is carried out following the De Vries method with a few modiftcations. The proportional counter presents some original constructive characteristics. The background is 1.75 cpm; the counting rate for modern carbon is 12.08 cpm; the efficient volume is 1.580 liters. The shields are 27 cm thick blocks of iron and blocks of paraffin mixed with boric acid. The hard component of cosmic rays is anticoincided by means of a plastic scintillator. (auth)
