This paper reports on the combination of the principles of molecular diffusion, physical adsorption, and spectroscopic detection in the development of a new personnel dosimeter. This dosimeter is designed to monitor personnel exposure of workers to potentially hazardous vapors and fine aerosols of polynuclear aromatic (PNA) compounds. This dosimeter collects the PNA compounds via molecular diffusion and sorption. Collection is followed by direct identification and quantification of the analyte compounds via the room temperature phosphorescence (RTP) technique. There is no requirement for a prior chemical extraction or chemical desorption protocol. Results on the evaluation of the dosimeter for various homocyclic as well as heterocyclic PNAs during laboratory-controlled experiments and field tests are be illustrated. The suitability of this device as a new personnel monitor in the workplace is discussed. 11 references, 6 figures.
