4Absorbed dose is broken out into SAA and GCR contributions, estimated based on the ISS trajectory and a geomagnetic field model
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:
- Data for internal NASA use or for use by NASA-funded or outside investigators are to be obtained directly from the GLDS (https://genelab.nasa.gov/environmental/radiation)
- Use of the data in publications or presentations shall require:
- Consultation with SRAG for data integrity and interpretation.
- Acknowledgement of one or more subject matter experts from SRAG.
