摘　　要：介绍了能谱型核测井仪的设计方案，其目标是研制适用于铀矿勘查的便携式测井仪，满足测井生产的需要。该仪器采用碲锌镉CdZnTe半导体核辐射探测器，高端的32位嵌入式ARM处理器S3C2410A为仪器系统控制核心，并在此硬件平台上移植了嵌入式Linux操作系统，编写了基于MiniGUI的测井仪监控终端软件。仪器具有实时性、体积小、功耗低、灵敏度高、成本低、便于携带等特点。This paper introduces a design project of energy spectrum nuclear logging instrument,the purpose of such instrument was to provide a portable device suitable to the prospecting and exploration of uranium deposit. This instrument uses CdZnTe detector as nuclear radiation detector and $3C2410A, a 32-bit high performance embedded ARM processor, as m/cro processor unit. Based on this hardware platform, embedded Linux system is ported. The monitoring ;ystem of nuclear logging instrument is developed by using MiniGUI. The instruments carry the characteristic of small size, low power, high sensitivity, low cost, and outstanding portability.
