RADIOACTIVITY MEASURING DEVICE WITH A MOVABLE DETECTOR HEAD

摘要

A radioactivity measuring device having a movable detector head for use in measuring the level of radioactivity in a multiplicity of discrete samples. The samples depend in a lateral array from a sample bearing means in a mounting frame, and the detector head undergoes translational motion to traverse the lateral array. The detector head moves vertically between a raised position for measuring radioactivity in samples, and a lowered position, for lateral movement beneath the array of samples. The detector head may accommodate simultaneously a plurality of samples for concurrent measurement, and the samples may be arranged in trays having a unique identification.
