Doses are in water based on standard conversion from dose in silicon.

Doses include approximate dose received on launch vehicle before transfer to the ISS.  Since there was no dosimetry on the launch vehicle, dose is approximated based on average values in the US Lab.

Data are cumulative absorbed doses from preliminary analysis of results from instruments on the International Space Station, analyzed by subject matter experts from the Space Radiation Analysis Group (SRAG), NASA-JSC. (https://srag.jsc.nasa.gov/)

For more detailed data, contact SRAG, through GeneLab: https://genelab.nasa.gov/help/contact

Use of the data are subject to the following rules:

  • Consultation with SRAG for data integrity and interpretation.
  • Acknowledgement of one or more subject matter experts from SRAG.
