The  TESLA Accelerator installation will produce 30 Mev and 70 MeV protons on first and second channel. Both of them will be used for complex experiments in which protons with arbitrary energy spectra will pass through many different materials. This was the principal motive for developing an operative software for proton transport simulations, working in three dimensions and for different materials.  We present here the last versions of SRNA code  ( Serbian text) developed for proton dosimetry and for proton therapy.
