Summary

A personal colorimetric dosimeter for nitrogen dioxide has been developed. Detector strips are prepared by dipping Eastman Chromagram Sheet, Type K301R2, in a solution of diphenylamine and oxalic acid in methanol. When dry, the strips can be used to estimate the concentration-time product to which an individual has been exposed. The strips are sensitive to heat and light. Nitrogen dioxide develops a green color while other oxidizers develop a blue color. The strips are not affected by moisture and should have a shelf life greater than one year. Color standards for concentration-time products of 50, 100, and 300 ppm-minutes and a blue standard to indicate an expired strip are described. A plastic holder for the sensitive detector strips is shown.
