Brief Description:
SHIELDOSE is a computer code for space-shielding radiation dose calculations.
It determines the absorbed dose as a function of depth in aluminum shielding
material of spacecraft, given the electron and proton fluences encountered in
orbit. The code makes use of precalculated, mono-energetic depth-dose data
for an isotropic, broad-beam fluence of radiation incident on uniform aluminum
plane media. These precalculated values are the result of detailed electron
and electron-bremsstrahlung Monte Carlo calculations. The present version of
SHIELDOSE calculates, for arbitrary proton and electron incident spectra, the
dose absorbed in small volumes of the detector materials Al, H2O
(tissue-equivalent detector), Si, and SiO2, in the following aluminum shield
geometries: (1) in a semi-infinite plane medium, as a function of depth; (2)
at the transmission surface of a plane slab, as a function of slab thickness;
and (3) at the center of a solid sphere, as a function of sphere radius.
