Abstract: The Xcounts algorithm for calculating air concentrations of radioactive xenon isotopes (Eslinger et al., 2023) has been extended to estimate <superscript>127</superscript> Xe in addition to <superscript>131m</superscript> Xe, <superscript>133m</superscript> Xe, <superscript>133</superscript> Xe, and <superscript>135</superscript> Xe. The algorithm was applied to 119 samples collected with a SAUNA Q <subscript>B</subscript> system (Ringbom et al., 2023) during a two-month atmospheric tracer release experiment. The algorithm identified two samples with <superscript>127</superscript> Xe present from a single 1.5 h release about 3.5 km upwind of the sampler and no false detections of <superscript>127</superscript> Xe were observed in the other samples.<br />Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.<br /> (Copyright © 2025.
