  The radiation from extreme Reissner-Nordstr\"{o}m black holes is computed by
explicitly considering the collapse of a spherical charged shell. No neutral
scalar radiation is found but there is emission of charged particles, provided
the charge to mass ratio be different from one. The absence of thermal effects
is in accord with the predictions of the euclidean theory but since the body
emits charged particles the entropy issue is not the same as for eternal
extreme black holes.
