For a large class of self-similar random sets F in R^d geometric parameters C_k(F), k=0,...,d, are introduced. They arise as a.s. (average or essential) limits of the volume C_d(F(epsilon)), the surface area C_{d-1}(F(epsilon)) and the integrals of general mean curvatures over the unit normal bundles C_k(F(epsilon)) of the parallel sets F(epsilon) of distance epsilon, rescaled by epsilon^{D-k}, as epsilon
ightarrow 0. Here D equals the a.s. Hausdorff dimension of F. The corresponding results for the expectations are also proved.
