Space Radiation Quality Factors and the Delta Ray Dose and Dose-Rate Reduction Effectiveness Factor
Abstract
In this paper, the authors recommend that the dose and dose-rate effectiveness factor used for space radiation risk assessments should be based on a comparison of the biological effects of energetic electrons produced along a cosmic ray particles path in low fluence exposures to high dose-rate gamma-ray exposures of doses of about 1 Gy. Methods to implement this approach are described.

More recent versions of the NSCR model suggest the possibility of a much higher risk than 3% fatality at 600 mSv for 35-year-old females.

Protraction effects would not be important for space missions because of their limited duration and dose-rate effects distinct from low-LET radiation due to the small number of heavy ion traversals per cell.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
