研制的仪器是四道微分γ能谱仪。它由一个控制台和一个带有声75mm×75mm碘化钠晶体的探测器组成,能自动稳谱,自动定时测量,自动计算U,Th,K含量及其比值,手动或自动存储原始测量参数。它设有掉电保护,可重复读出或通过RS-232接口与计算机连接作进一步处理。所有工作由触摸式按键输入指令,由单片机软件程序控制自动完成。该仪器能用于放射性地质填图,放射性元素的地球化学研究,岩石与矿物样品中放射性元素做快速分析,U,Th,K的勘探与普查,环境监测,以及用于寻找金矿等。
Developed instrument is four differential gamma spectrometer. It consists of a console and a detector with a 75mm × 75mm crystal of sodium iodide that automatically stabilizes and automatically measures the time, automatically calculates the U, Th, and K contents and their ratios and stores the original measurement parameters manually or automatically. It has a power-down protection, read repeatedly or through the RS-232 interface and computer connection for further processing. All the work is input by touch keys, controlled by MCU software program automatically. The instrument can be used for radioactive geological mapping, geochemical studies of radioactive elements, radioactive elements in rock and mineral samples for rapid analysis, U, Th, K exploration and census, environmental monitoring, and for the search for gold and so on.
