一、概述 FD-840四道自动能谱仪是一种便携式耗电省的精密野外仪器。本仪器具有自动稳谱、自动定时、连续取样、含量自动运算、总量灵敏度可调、异常自动报警等多种功能。它能同时直读铀、钍、钾含量及总量强度。也可同时显示铀、钍、钾计数率及其中任选一种元素的含量。本仪器可用于:1) 放射性地质填图、普查找矿;2) 放射性地球化学研究;3) 放射性环境测量等。
I. Overview FD-840 four-channel automatic spectrometer is a portable power-saving precision field instruments. The instrument has automatic steady spectrum, automatic timing, continuous sampling, content automatic calculation, the total sensitivity adjustable, abnormal automatic alarm and other functions. It can simultaneously read uranium, thorium, potassium content and the total intensity. Can also show the uranium, thorium, potassium count rate and the content of any one of the elements. The instrument can be used: 1) radioactive geological mapping, prospecting prospecting; 2) radioactive geochemical research; 3) radioactive environmental measurements.
