Artificial radiation belts are radiation belts that have been created by high-altitude nuclear explosions.
The table above only lists those high-altitude nuclear explosions for which a reference exists in the open (unclassified) English-language scientific literature to persistent artificial radiation belts resulting from the explosion.
The Starfish Prime radiation belt had, by far, the greatest intensity and duration of any of the artificial radiation belts.
The Starfish Prime radiation belt damaged the United Kingdom Satellite Ariel 1 and the United States satellites, Traac, Transit 4B, Injun I and Telstar I. It also damaged the Soviet satellite Cosmos V. All of these satellites failed completely within several months of the Starfish detonation.
Telstar I lasted the longest of the satellites damaged by the Starfish Prime radiation, with its complete failure occurring on February 21, 1963.
