  We study the stability of the reconstruction of the scattering and absorption
coefficients in a stationary linear transport equation from knowledge of the
full albedo operator in dimension $n\geq3$. The albedo operator is defined as
the mapping from the incoming boundary conditions to the outgoing transport
solution at the boundary of a compact and convex domain. The uniqueness of the
reconstruction was proved in [M. Choulli-P. Stefanov, 1996 and 1999] and
partial stability estimates were obtained in [J.-N. Wang, 1999] for spatially
independent scattering coefficients. We generalize these results and prove an
$L^1$-stability estimate for spatially dependent scattering coefficients.
