Development of a Dosimeter for Personnel Exposure to Vapors of Polyaromatic Pollutants

A new personnel dosimeter based on molecular diffusion and direct detection by room temperature phosphorescence (RTP) has been developed to monitor vapors of polynuclear aromatic (PNA) pollutants. The dosimeter is a simple, pen-size device that requires no sample extraction for analysis. By proper calibration of the dosimeters, the time-weighted average exposure to the pollutants can be determined directly on the sample collection substrate. The dosimeters can detect a variety of PNA compounds such as pyrene, phenanthrene, and quinoline at 2.5, 0.5, and 0.75 ppb vapor concentrations, respectively, after 1 h of exposure. © 1985, American Chemical Society.
