Radioprotection and the Argon 41 Formed in the Reactors G 1 and G 2/G 3 (La Radioprotection et L 'Argon 41 Forme Dans les Piles G 1 et G 2/G 3)

摘要

The activation of argon 40 present in the air or in trace form in CO2 is particularly important. In G 1 the cooling is effected by atmospheric air which passes through the reactor and is expelled through a chimney. The activity due to argon 41 of the expelled air is about 0.0001 Ci/cu.m. For the reactors G 2 and G 3 the cooling is effected using CO2 in a closed circuit at a pressure of 15 kg/sq. cm. Although the argon content of industrial CO2 is practically constant, it can be influenced by that of the residual air left in the circuits during the start-up. The activity due to argon 41 of the heat-carrying fluid is about 0.001 Ci/cu.m. (Author)
