  In this paper we calculate the energy distribution of six cases of
Vaidya-solutions in the M{\o}ller prescription. Except the energy complex of
M{\o}ller for the monopole solution vanishes everywhere, for other solutions
have non-zero energy component, only the energy distributions of the de Sitter
and anti-de Sitter solution are independent on $v$. For the radiating dyon
solution, the difference in energy complex between M{\o}ller's and Einstein's
prescription is like the case of Reissner-Nordstr\"{o}m solution.
