Abstract: In the technical field of power generation, a method and system for directly and rapidly detecting 14C of carbon dioxide, which can quickly complete a 14C activity measurement of carbon dioxide, while further improving uniformity and accuracy for directly and rapidly detecting 14C of carbon dioxide. The method includes: pressurizing and liquefying gaseous carbon dioxide to obtain liquid carbon dioxide; mixing the liquid carbon dioxide with a cosolvent and a scintillator in a pressure vessel to obtain a mixed solution; and placing the pressure vessel in a liquid scintillation counter for carrying out radiocarbon activity detection.
