A method for the calculation of the energy losses of heavy charged particles in a low energy region (<1 MeV/nucleon) for the plastic nuclear track detectors is described. The method is based on the fundamental relation (dE/dx)/ sub ion/ = (Z/sub eff// gamma /sub p/)/sup 2/(dE /dx)/sub proton/ (Z/sub eff/ and gamma /sub p/ are the effective charges of heavy ions and protons, respectively). The stopping power of a given plastic detector for the proton was obtained from the atomic stopping powers of the individual constituent elements for the proton, which are derived from the existing data for other organic compounds in solid state, assuming the Bragg's additivity rule. Then, the energy loss rates of heavy ions in the plastic detectors were calculated from the above relation, using the formulas for the effective charges. The range-energy relations, obtained by this method, for fission fragments in polycarbonate resin and cellulose triacetate were in good agreement with the experimental results. (auth)
