AB A method for monitoring room air for radioactive xenon gas is described. It uses activated charcoal vials, a vacuum source and a well-type scintillation counter. The method may be adapted for detection and identification of any radioactive gas excluding those with ultra-short half-lives. Sampling room air during xenon-133 (133Xe) ventilation lung studies was performed using this technique. The results show that low concentrations of 133Xe in room air can be reliably detected and that staff exposure to 133Xe at this institution was within ICRP recommendations.
