Satellite Radiation Dose Rate

Jan 13, 2024 Last reply: 2 years ago 2 Replies

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.
