Abstract: A measuring roller for determining a property of a strip-shaped material such as metal strip, passed over a measuring roller, having a measuring roller body with a circumferential surface, at least one recess in the measuring roller body, which is arranged at a distance from the circumferential surface or leads from the circumferential surface into the interior of the measuring roller body, and with a first force sensor arranged in the recess and a second force sensor arranged in the recess or in a further recess adjacent to the recess, wherein the first force sensor has a sensor surface and the first force sensor can generate a sensor signal when the position of the sensor surface of the first force sensor changes, and the second force sensor has a sensor surface and the second force sensor can generate a sensor signal when the position of the sensor surface of the second force sensor changes.

Abstract: A method for correctly identifying at least one source, in particular at least one nuclide, enclosed in a human body and/or a container, is provided, the method comprising the following steps: detecting and measuring the at least one source by means of a gamma spectroscopic device; identifying, in a first estimation step, the at least one source by means of a standard nuclide identification procedure for evaluating a measured first spectrum of the at least one source; applying a second estimation step on the basis of the result of the first estimation step, wherein the result of the first estimation step is used for acquiring a plurality of second spectra of the at least one source found by the standard nuclide identification procedure for a plurality of absorption scenarios and for a plurality of scattering scenarios; and comparing the measured first spectrum with a scatter and absorber spectrum obtained from the plurality of second spectra generated in the second estimation step.
