Abstract
A dosimeter for detection of noxious substances which are collected on a plaque-like substrate carrier, which is closed off against the outside by a diffusion membrane fitted to it, is improved so that a uniform fit can be achieved over the entire surface of the membrane. For this, the substrate carrier is curved outwardly.
