Abstract Considering energy conservation and the backreaction of particles to spacetime, we investigate the massless/massive Dirac particles' Hawking
radiation from a Schwarzschild black hole. The exact expression of the emission rate near the horizon is obtained and the result indicates that Hawking radiation spectrum is not purely thermal. The result obtained is consistent with the results obtained before. It satisfies the underlying unitary theory and offers a possible mechanism to explain the information loss paradox. Whereas the improved Damour--Ruffini method is more concise and understandable.
