Summary

Space radiation exposure was measured using passive and active detectors on STS missions. Radiation dose rates varied by position, but overall exposure remained consistent during solar minimum.

Area of Science:

  • Space science
  • Radiation biology
  • Astrophysics

Background:

  • Space missions expose astronauts and equipment to unique radiation environments.
  • Understanding space radiation is crucial for crewed missions and sensitive experiments.

Purpose of the Study:

  • To characterize the radiation environment within the Biorack facility on multiple space shuttle missions.
  • To assess dose rates, particle fluences, and linear energy transfer (LET) from galactic cosmic rays (GCR) and trapped particles.

Main Methods:

  • Utilized a dosimetric package including passive detector stacks (plastic nuclear track detectors, thermoluminescence detectors) and active DOSTEL units with silicon detectors.
  • Exposed detectors at various locations within Biorack incubators across STS-76, STS-81, and STS-84 missions.
Keywords:

  • Analyzed data for dose measurements, particle fluence rates, neutron doses, time-resolved particle counts, dose rates, and LET spectra.

    • Main Results:

    • Mission-integrated doses were similar across flights due to solar minimum conditions.
    • Observed dose rate variations up to a factor of two based on detector position within Biorack.
    • DOSTEL units provided time-resolved data and LET spectra, enabling separation of GCR and trapped particle contributions.
    • Investigated radiation field anisotropy using dual DOSTEL units on STS-84.
    • Mean quality factors (Q) averaged 2.0±0.1, with deduced dose equivalent rates ranging from 631 to 716 µSv/day.

    Conclusions:

    • The radiation environment inside Biorack is spatially heterogeneous, with significant positional variations in dose rate.
    • Passive and active dosimetry provide complementary data for comprehensive radiation assessment in space.
    • Findings contribute to understanding long-term space radiation exposure risks for biological experiments and future crewed missions.
