Cosmic ray dosimetry was measured during the IBIS facility

Area of Science:

  • Space science and radiation physics.
  • Dosimetry and radiation detection.

Background:

  • Accurate measurement of cosmic radiation is crucial for space missions.
  • Understanding the contribution of different radiation components (low and high LET) is essential for risk assessment.

Purpose of the Study:

  • To perform dosimetry of cosmic rays during the first experimental flight of the IBIS facility.
  • To determine the linear energy transfer (LET) spectra of charged particles.
  • To assess the absorbed dose and dose equivalent rates.

Main Methods:

  • Utilized thermoluminescent detectors (TLD) for low LET radiation (< 10 keV/micrometer).
  • Employed plastic nuclear track detectors (PNTD) for high LET radiation.
  • Measured track parameters to determine LET spectra of primary and secondary charged particles.

Main Results:

  • The total absorbed dose rate was 0.23 mGy/day.
  • The dose equivalent rate, using ICRP 60, was 0.52 mSv/day.
  • The mean quality factor was determined to be 2.4.

Conclusions:

  • The dosimetry results are consistent with previous measurements from the MIR station.
  • The combined TLD and PNTD approach effectively characterized cosmic ray radiation environments.
  • The findings provide valuable data for radiation protection in space exploration.
