FD-3022四道γ能谱仪测量过程及常见问题浅谈

Discussion about the Measurement Process of FD-3022 γ Spectrometer and the Common Problems

FD-3022能谱仪是铀资源勘查和核技术应用领域常见的一种γ能谱仪,广泛用于放射性矿床和其他金属和非金属矿床(如金矿、石油等)的野外普查找矿工作,也可做填图等其他地质研究,水文地质调查和环境监测等工作。仪器经标定后还可进行天然石材放射性测量。随着铀资源勘查任务的增加和核技术应用领域的拓展,仪器数量和使用人数不断增加,一些仪器故障、使用注意事项等困扰新手的问题也随之出现。错误的操作不仅影响了仪器的使用寿命,也耽误了项目进度。针对该仪器在计量检定和野外测量使用过程中常见的一些问题,进行了分析和归纳,并给出了参考的解决方法。

FD-3022 is a common y spectrometer on the application field of prospecting uranium and nuclear technique.Widely used in radioactive mineral deposits and other metal and non--metallic deposits （such as gold, oil, etc.） field reconnaissance prospecting work. Also do the mapping and other geological research, the hydrogeological survey and environmental monitoring work. The instrument can be natural stone of radioactive measurement after the calibration. With the increase of uranium resources exploration tasks and nuclear technology application development, also the new users and instruments increased, the perplexed problems of tyro have emerged,such as some instrument malfunctions and attention. Incorrect operation not only affects the life of the instrument, but also delayed the progress of the project. Aim to the common problems in measurement verification and practical survey, then made to analyse and induce,and gave the methods to solve the problems constantly.
