摘要：
Carbon-14 and tritium are important radionuclides to be present in gaseous effluents of some nuclear power plants types. Tritium being usually included in gaseous effluents bearing carbon-14, the influence of its presence in the analyzes to be done must carefully be taken into account. When Liquid Scintillation Counting method is used, this influence can't be completely eliminated by selecting different channels only for measuring carbon-14. In this paper, experimental verification of the influence of tritium on the carbon-14 measurements also miscibility of samples, detection efficiency and measurement precision were studied.
