A prototype multidetector shadow-shield whole-body counter is presented to be used as a monitor of internal contamination and as a tool in clinical research. The counter is equipped with 16 NaI(Tl) detectors located in the central region of a shielded tunnel surrounding the subject to be measured. The accuracy of the counting efficacy predictions was tested in a group of adults with various body shapes and sizes using X-ray absorptiometry. The precision of the total body potassium measurements allows the use of the counter in clinical follow-up studies.
本文介绍了一种原型多探测器阴影屏蔽全身计数器，它可用于监测体内污染，并作为临床研究的工具。该计数器配备了16个碘化钠（铊）探测器，位于围绕被测对象的屏蔽隧道的中心区域。使用X射线吸收测定法在一组具有不同体型和尺寸的成年人中测试了计数效率预测的准确性。全身钾测量的精度使得该计数器可用于临床随访研究。
