Abstract An analysis of the influence of low energy charged particles onto the surface charging doses of spacecraft was conducted using data from ACTIVE (InterCosmos 24) satellite, SPRUT-VI experiment on board MIR station and the SAMPEX satellite. The surface doses were calculated in the materials up to 10–20 μm in depth. The obtained results were compared against the AE 8 model and a conclusion was reached that the contribution of “abnormal” (i.e., unaccounted in the models electron peaks at L < 2) electron fluxes in the surface dose is insignificant at altitudes less than 600 km.
