Zusammenfassung:	This paper reports the brief process and results of radioxenon monitoring and analysis in Beijing following the Fukushima Daiichi nuclear power plant accident. The accident and release of volatile radionuclides were caused by 9.0 magnitude earthquake and tsunami on March 11, 2011. The maximum concentrations of 133Xe and 131mXe were in excess of 0.90Bq.m−3 and 0.047Bq.m−3, respectively. The activity ratio of 131mXe to 133Xe and the dynamic trend of 133Xe activity concentration were analyzed.
