tracer gas

Contaminant dispersion and dilution in a ventilated space.

Parameters were contaminant source location, sample location and ventilation rate. Measures equilibrium concentrations and rates of decrease in concentration following cessation of tracer release. Subjects data to multifactorial analyses.
