  The Keski-Vakkuri, Kraus and Wilczek (KKW) analysis is used to compute the
temperature and entropy in the dyadosphere of a charged black hole solution.
For our purpose we choose the dyadosphere region of the Reissner-Nordstrom
black hole solution. Our results show that the expressions of the temperature
and entropy in the dyadosphere of this charged black hole are not the Hawking
temperature and the Bekenstein-Hawking entropy, respectively.
