  • COL - ESA Module ("Columbus")
  • JPM - Japanese Pressurized Module (part of "Kibo")
  • LAB - US Lab ("Destiny")
  • NOD1, NOD2, NOD3 = Nodes, which connect the elements of the ISS.
    • Node 1 ("Unity") connects the U.S. and Russian segments.
    • Node 2 ("Harmony") connects the U.S., European, and Japanese laboratories, as well as PMA-2.
    • Node 3 ("Tranquility") is attached to the port side of Node 1 and provides accommodation for life-support equipment.
  • SMP = Russian Service Module ("Zvezda")

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/)
