The real time finite temperature Green functions necessary for perturbations in general relativity are obtained in the scheme of thermo field dynamics. As an application, the author calculates the one-loop effective potential in the real scalar theory in the general curved space background in the normal coordinate expansion. The author also provides a basic formula needed for evaluating the transport coefficients by calculating the imaginary part of a scalar self-energy diagram.
