Abstract

PURPOSE:To accurately detect the radioactivity of a specimen regardless of the variation in the quantity of the specimen collected into a sample container by moving the sample container and a radioactivity detector relatively to each other, and integrating the detector output during said moving period. CONSTITUTION:A sample container 1 is first set in the position shown by a dotted line in the figure and then lowered to the position shown by a solid line as a driving mechanism 4 lowers according to the instructions from a controller 8. At the same time, a counter 7 performs integration of the scintillator output counting rate during said moving period. The measurement starting and stopping signals to the controller are provided in synchronization with the arrival of a sample by means of a separate controller, memory device or the like. In addition, a similar efficiency can be obtained by a method wherein a spot-type radioactivity detector is provided on the said of the sample container, and while said detector is being moved in the axial direction of the container, relatively thereto, the counting rate integrated value is measured.
