Abstract:

A research program was initiated to develop a personal colorimetric dosimeter for hydrazine fuels. An extensive literature survey was conducted to ascertain the most appropriate colorimetric reactions applicable to such a device. Many reagents were found which formed a color upon contact with various hydrazine vapors however, most of these colored reaction products proved unstable during accelerated aging tests. Bindone, delta 1,2 -- Biindan--1, 3,3 -- Trione, uniformly dispersed on Eastman Chromagram Sheet Type K301R2 was selected for incorporation as the sensing element in the dosimeter badge, because its response to hydrazine, unsymmetrical dimethylhydrazine UDMH, and monomethylhydrazine MMH was both linear and readily observable. Synthetic color standards were developed and included in the dosimeter to provide the user with a means of estimating accumulated exposure within the range of 100-1800 ppm-minutes.
