A Monte Carlo method is used in order to calculate the response (tracks⋯cm-2 ⋯ μSv-1) of a fast neutron dosemeter, composed of a polyethylene radiator and CR-39 plastic track detector, to monoenergetic neutron beams at normal incidence and taking into account the electrochemical etching conditions. The method is applied to neutrons having energies in the range 0.08-10 MeV. The total number of protons emerging from the radiator is calculated, as well as their energetic and angular distribution. Detection efficiency as a function of proton energy and angle is taken into account. The theoretical calculation is compared with experimental results obtained for Am-Li and Pu-Be sources for protonic equilibrium radiator thicknesses. © 1991.
