Abstract

We discuss an in-situ evaluation of the $^{85}$ Kr, $^{222}$ Rn, and $^{220}$ Rn background in PandaX-I, a 120-kg liquid xenon dark matter direct detection experiment. Combining with a simulation, their contributions to the low energy electron-recoil background in the dark matter search region are obtained.
