  • Satellite Radiation Dose Rate

    From Artist@21:1/5 to All on Fri Jan 12 22:41:46 2024
    I am seeking data on what radiation doses electronics on a satellites
    get in both low, and high, earth orbits. I need this in units of Gray
    (Gy), or rem.

    I know radiation exposure will change depending on Solar Cycle Phase,
    and the orbit, especially if polar, and also when passing over the South Atlantic Anomaly, and shielding. What I need is typical exemplar data
    for a short mission of one hour, and a long mission of many years,
    preferably collected from actual satellites. If you have this
    information please include the source.

    Your help will be much appreciated.

    Fig 1 of this paper shows something in the South Atlantic.

    Fig 3 of this paper part answers your altitude question:
