Heavy particle fluxes in Salyut space station orbit.

Results of a detailed analysis of heavy ion fluences measured on the Salyut and MIR orbital stations from 1978 to 1990 are presented. The analysis has made use of new models that describe the cosmic ray fluxes and their transition through the magnetosphere. The penetration of solar cosmic ray particles to the orbit, the increase of the (Sc-Cr)/Fe flux ratio in the orbit, and the occurrences of 200-500 MeV/nucl heavy nuclei in <30 degrees latitudes have been analyzed.
