This article introduces a new method to measurement the activity of radioxenon isotopes.The plastic tube-type gas cell and samples transfer apparatus were researched and manufactured.Peak efficiency of well-type HPGe detector was calibrated with the archive sample of CTBT noble gas exercise.The minimum detectable activity reaches 10.2 mBq to 81 keV gamma ray of 133Xe in 24 h measurement time.
