Consideration is given to neutron and nuclear gamma-ray generation during the June 3, 1982 event. In the proposed model, the secondaries are generated by accelerated ions moving inside a magnetic loop structure in an inhomogeneous solar atmosphere, taking into account the particle scattering on MHD waves generated by exterior sources, as well as by the accelerated protons themselves. It is shown that observational data on high-energy MeV neutrons and nuclear gamma rays can be fully explained within the framework of the model, provided the whole lot of particles undergoes acceleration during the impulsive phase of the event. Observational data on high-energy neutrons obtained by means of neutron monitors are also in accordance with the assumption that all the secondary nuclear emission was generated by particles of the same population.
