Reviews qualities desirable in a tracer gas for the measurement of ventilation rates in buildings. Reports experiments in which radioactive argon was used to measure the ventilation rate in a room. Results obtained agreed with simultaneous measurements using hydrogen as tracer. Suggests use of method for measuring ventilation rates in large buildings and use of krypton gas as an alternative to argon.
