We present the results of a comparative analysis on the efficiency of the solar energetic particle events (SEP) and related solar flares. Both SEP events and solar flares were detected by the CORONAS-F solar mission. We selected the SEP events based on the presence of simultaneous observations from the hard X-ray (HXR) instrument SONG (CORONAS-F satellite) with radio emission ranging from microwaves to the meter-range, as evidence of accelerated particles generated during the events and solar proton and electron data measured by MKL instrument on board CORONAS-F satellite in polar caps. The results are discussed from point of using solar flare emission features as the criteria of generation of SEP event with high proton abundance.
