Experiment: RADIUS-M
RADIATION/DOSIMETRY CONTROL COMPLEX
STUDY OF RADIATION CONDITIONS IN THE INTERPLANETARY SPACE
Main scientific objectives:
study of radiation conditions along flight trajectories to Mars and near the planet;
timely forecast of the spacecraft irradiation dose;
dosimetric control on board the spacecraft;t
processes of generation and propagation of charged particles in the interplanetary space;
estimation of meteorite hazard to a spacecraft.
Complex should:
measure Sun's X-ray fluxes within 2 to 200 keV, estimate the energy of solar X-ray bursts;
determine the energy spectra and spatial distribution of charged particle fluxes within energy ranges: 0.07-1.5 MeV (for electrons), 0.05-200 MeV (for protons), 2-40 Mev/nucleon (for heavy nuclei in the charge range 2
determine an integral dose and its rate as well as spectra of linear losses of charged particle energy within 500 keV/ m; behind 0.1 mm, 1.0 mm, 10 mm Al protection screen,
measure the density of micrometeoritic particle flows velocity range 3-35 km/s; mass range 5x10-4 - to 10 -9 g, and for charge of particles from 10-14 to 10-9 C.
