[Results of measuring the charge and energy spectra of heavy nuclei on board the artificial Earth satellite Kosmos-936].

The measurements were performed using a package of dielectric track detectors mounted behind the shield of 60-80 kg.m-2 thick. The charge of nuclei was determined from the complete track length.

LET variation measurements behind different absorber thicknesses on COSMOS-1129 satellite.

LET variation with the absorber thickness was measured by plastic detectors exposed on COSMOS-1129 satellite.
