The thermo field dynamics formulation of quantum fields in the presence of eternal Schwarzschild black holes, which was presented by Israel (1976) in the free case, is extended to the case of self-interacting fields. With this formulation, the authors calculate the dissipative coefficient for an excited quantum particle in an equilibrium distribution. The result shows that the quantum particle dissipatively disappears with an infinitesimal lifetime near the event horizon and with a constant lifetime far from the horizon.
