We present results on opacity and radiation losses of mid-Z impurities in ICF conditions. Two approaches were investigated. The first one is based on a detailed calculation where the atomic database is provided by the MCDF code. Then a lineshape code (PPP) based on a fast algorithm was adapted to the calculation of emissivity and opacity profiles. The second approach is a statistical one. It involves high-order moments of the radiative power losses. Atomic calculations were performed with the Cowan code. The Normal Inverse Gaussian and the Generalized Gaussian distributions were then used to calculate the radiation power loss profile.
