Radiative transfer through random media is studied into an abstract Banach
space setting. The attention is focused on systems whose stochastic behavio
ur can be described by means of a finite number of random parameters, such
as a cloud with stochastic clumps. By using two different projection method
s, sequences of evolution equations, which approximate the exact equation f
or the expectation, are deduced. (C) 2000 Elsevier Science Ltd. All rights
