Atmospheric 81Kr as an Integrator of Cosmic‐Ray Flux on the Hundred‐Thousand‐Year Time Scale

Abstract The atmospheric abundance of 81Kr is a global integrator of cosmic rays. It is insensitive to climate shifts, geographical variations, and short‐term solar cycle activity, making it an ideal standard to test models of cosmic‐ray flux on the time scale of 105 years. Here we present the first...
