The right-handed neutrino cross sections of the processes νL + l --> νR + l and νR + l --> νR + l, where l is a relativistic lepton, are calculated in the SU(2)L × SU(2)R × U(1) model. According to a cosmological criterion the parameters of the model are bounded. In particular we obtain the bound MWR >~ 30 MWL, assuming the neutrinos are Dirac four-component particles.
