Principal Investigator
Research Area:
Radiation biology
Species Studied
Scientific Name: Not applicable Species: Not applicable

Description
Objectives:

This experiment measured radiation under five conditions: 1) depth dose under very thin shielding on the outside of the spacecraft; 2) low energy, heavy particle LET spectra under very low shielding (outside the spacecraft); 3) the neutron spectra inside and outside the spacecraft; 4) high energy (> 1 MeV) neutron fluxes and dose equivalent rates averaged over mission duration ( 0.2 eV) and resonance (0.2 eV < E < 1 MeV) neutron fluxes and dose equivalent rates over mission duration.
