Abstract
A method for reading and analyzing a diffusion-cell colorimetric exposimeter for making a quantitative determination of the time-weighted average (TWA) exposure to airborne gases or vapors. The diffusion cell is optically scanned to form color video signal data representative of the primary color components of the image formed from the reaction of the chromophoric reagent and pollutant. The data is converted to digital data and processed to compute exposure for a given pollutant gas as a function of color intensity for at least one of the primary color components.
