DOSEFIELD turns galactic-cosmic-ray ion spectra into absorbed dose and dose-equivalent behind spacecraft shielding, from first principles — Bethe–Bloch stopping power, ICRP-60 quality factors, a cited GCR model. Every constant is sourced and cited, nothing is tuned to the answer, and the result is validated against NASA’s MSL/RAD Mars-cruise measurement.

Deterministic 1-D slab · stopping power within — of NIST PSTAR (≥10 MeV) · integral cruise dose within ~2× of MSL/RAD · primaries + simplified Bradt–Peters fragmentation, no secondary-neutron transport — not a substitute for HZETRN / OLTARIS.
