1. A method for directly and rapidly detecting 14C of carbon dioxide, comprising:
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 a detection of a radiocarbon activity.
