N2 - A simple badge type diffusion tube, 35 mm photo film plastic case, was used for evaluating time-weighted exposure to H2S using reagent impregnated filters (Whatman No. 1). The black shade of the reagent filter, 10% Pb(OAc)2 and 2% AgNO3 under the concentration of H2S below 20 ppm for 2 to 4 hours agreed inversely to the diffusion length of the tube, and lineally well correlated with dose-time unit (CxT. and the theoretical value of diffusion. The device was proved to be capable of being used in realistic working conditions provided that there is no extreme fluctuations of H2S.
