Dosimetry results of COSMOS 1887.

The objective of the experiment was to measure the radiation environment inside and outside of the biosatetlite COSMOS 1887. For this purpose, detector packages were built up consisting of plastic detectors and nuclear emulsions having different linear energy transfer (LET) thresholds in particle registration, and thermoluminescence dosimeters (TLD). Particle fluence rates, LET-spectra and absorbed dose are presented. Absorbed dose is measured as a function of shielding depth. The data are compared with those of other missions.
