Abstract: The inert gas monitoring results are generally lower than the detection limit onnormal operating conditions, if relevant monitoring results lower than the detection limit, half of its emissions by statistical detection limit may overestimated the annual emissions. By determining activity proportional relationship of85Kr and 133Xe, when the 85Kr of maximumhalf-lifein the inert gas source term was less than the detection limit, its activity concentration can estimate indirectly. Thus the annual emissions statistics of 85Kr can obtained more objectively.

Key words: Emissions statistics, Proportional relationship, 85Kr, 133Xe
