Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method and an apparatus for measuring14CO2fluxes at a boundary surface of an environmental medium, by using a flowing-gas technique. SOLUTION: An air chamber which has an inlet, an outlet and an aperture, is arranged so as to regulate an atmosphere space being in contact with a constant area of the boundary surface of the environmental medium, and concentrations of the14CO2fluxes are measured at the inlet and the outlet, and then they are evaluated by using the expression shown in figure.
