Radiation field formation and monitoring beyond LEO

As follow from the long-term discussion of relative role of solar flares and CMEs in SEP production, existing paradigm of particle acceleration at near the Sun should be considerably improved. Also, it should be undertaken a partial revision of some existing models for SPE occurrence rate, proton energy spectrum, etc. In fact, we need a new concept of SPE in precise terms, taking into account a set of physical constraints for SEP acceleration and release processes.
