Proton events accompanied by hectometric radio bursts have been analyzed on the basis of the PROGNOZ-8 satellite measurements. Proton fluxes with energies E>100 MeV andE > 500 MeV were recorded in April and May 1981 from the powerful flares developed in large sunspot groups which existed on the Sun during two solar revolutions.
