How much radiation can a Pi handle in space?

Mark Rober's team tested Raspberry Pi Compute Module 4 and Google Pixel 7 Pro radiation tolerance for their SatGus CubeSat mission. Using cyclotron testing at UC Davis and gamma testing at University of Maryland, they found the CM4 experienced single-event upsets every 39.3 Rads at 50 Rads/minute and survived until 57.8 kRads with permanent failure. The Pixel 7 Pro died around 9.2 kRads at high dosage. A 5mm aluminum enclosure provides shielding for the mission's expected 1-year lifespan in Low Earth Orbit. Standard Raspberry Pis work in space when not in critical flight paths, with watchdog timers handling radiation-induced reboots.
