The areas of energetic particle injection on the Sun from 1956 to 2013 are considered. A significant irregularity of their heliolongitude distribution have been found. A special attention is paid to the discovered region of “passive longitudes” with very law radiation effectiveness, extensive over the longitude (~90–170°) and the life time (the whole period of observations). Also the distribution of the sources of energetic solar protons measured in Earth’s orbit, over the longitude relative to the central meridian have been considered. The conclusion about the validity of the obtained data for estimation of the risk of solar cosmic ray arriving is made.
