  Applying Parikh's semi-classical tunneling method, we consider Hawking
radiation of the charged massive particles as a tunneling process from the
Reissner-Nordstrom-de Sitter black hole with a global monopole. The result
shows that the tunneling rate is related to the change of Bekenstein-Hawking
entropy and the radiant spectrum is not a pure thermal one, but is consistent
with an underlying unitary theory.
