Tracer gases and its monitoring method were studied in measurement of ventilation rate by use ofconcentration-decay method. Five kinds of gases (sulfur hexafluoride, nitrous oxide, carbon monoxide, carbon dioxide and isobutene) were compared.In this study isobutene was used as law-environmental-loading tracer gas. Its concentration was monitored with a PID (photo-ionizing detector) monitor.To fix the procedures and conditions for measurement of ventilation rate, the performance characteristics of this system were examined.
