Abstract
A sample-taking appliance comprises several sensors (61, 62, 63, 64) arranged on a turntable like sensor carrier (50) in such a manner that the application areas (68) of the small sensor sponges (67) decrease stepwise from the first to the last sensor. By simple rotation of the turntable the sensors (61, 62, 63, 64) can be brought successively into a working position. The sensor carrier (50) is preferably accommodated in a housing (25) which is open at the bottom and which is raisable and lowerable in the frame (5) of the appliance by, for example, a threaded spindle (41, 42). The threaded spindle (41) is driven by an electric motor (44). For each sampling the sensor carrier (50) is lowered until the cell voltage corresponds to a predetermined desired value. This produces sufficiently precise and reproductible measured values of the electrolytic current for ascertaining the removed layer thickness. The appliance makes it possible to take material samples even from locations of high radiation loading. The material layers removed as samples lie concentrically above each other so that the graduation of the application areas (68) comes into full effect and the material samples taken by the small sponges and the radioactivity contained therein are not falsified.
