N2 - We present the first AMS measurement of the 81Kr concentration in atmospheric krypton. The measurement was performed by combining positive-ion production in an electron cyclotron resonance source with acceleration to high energy in a cyclotron and subsequent full stripping for 81Br-81Kr separation. The result, 81Kr/Kr = (5.3 ± 1.2) × 10-13, agrees well with two previous low-level decay counting measurements.
