The generation of gamma radiation produced by the protons accelerated at shock fronts in young SN II envelopes is considered. The shocked gas is known to form the shell limited by the inner and outer shock fronts. The radiation results from p-p interactions inside the shell through production and decay of pions. The flux of gamma rays expected from SN II in the Galaxy are shown to be detectable. The signature of the considered mechanism is early production of the signal, whereas the radiation produced inside the envelope is emitted when transparency sets in. 32 refs.
