Abstract of the Disclosure The invention relates to a dosimeter wherein the substances to be detected color a chemical sensor layer. The degree of coloration of the chemical sensor layer is measured by a photometric diffusion-reflectance measuring device. This dosimeter is improved with respect to a measurement occurring during the time that the contaminant substance is effective. The foregoing is accomplished with the dosimeter of the invention in that the dosimeter has a measuring chamber which receives a diffusion element and with a light impermeable wall portion which closes off the diffusion element while at the same time being permeable to the substance to be detected. A light source and a photosensor are arranged in the measuring chamber.
