Zusammenfassung:An instrument is described for determining accurately the intensity of an x‐radiation by direct reading. This instrument consists in a small potassium iodide crystal which fluoresces under the action of high energy photons. The light thus emitted is ``piped'' by means of a Lucite rod to a photomultiplier tube. The current generated in the tube is measured by a microammeter. A series of tests on the energy dependence of this detector are reported. It is concluded that the instrument described is suitable for the determination of isodose charts.
