ABSTRACT:
A radiation measuring apparatus for performing measurements on samples contained in a plurality of sample containers disposed in the form of a matrix on a holder plate, the apparatus including a radiation detector having an entrance window, displacement devices for aligning successive sample containers with the entrance window of the radiation detector for automatic measurement of samples in the sample containers, the radiation detector and the sample containers being movable relative to one another in such a way that the sample container being measured and the entrance window of the detector are disposed coaxially with each other. The apparatus further includes: a diaphragm plate (10) provided with at least one aperture, the diaphragm plate being fixedly disposed between the entrance window (31) of the detector (30) and a sample container (21) placed underneath the entrance window; a component forming a light-tight coupling between a sample container (21) placed underneath the entrance window and the entrance window; and a component disposed for pressing the sample containers against the diaphragm plate (10) with a constant pressure while permitting the sample containers to be displaced parallel to the diaphragm plate by the displacement devices.
