CZD－6型车载多道γ能潜测量系统，以核工业北京地质研究院研制的HDY－256型便携式多道γ能谱仪为操作台，与大体积闪烁探测器构成γ能谱测量系统。每一测点的位置用GPS导航仪定位。测点的经纬度及该测点上获取的256道γ能谱数据用笔记本微机采集，可以在行进中实时显示每一测点的256道谱线。仪器安装在轻型越野车中，构成一套完整的车载多道γ能谱测量系统。该系统在石家庄航测放射性模型上通过校正后，已用于环境放射性监测。获得的大量数据表明，仪器性能稳定，工作可靠，是快速进行环境γ能谱测量的先进手段。它不仅可用于测定环境天然放射性元素浓度，而且在核事故应急处理、核污染监测中具有重要意义。
CZD-6 multi-channel γ-car latent measurement system for vehicles, with the HDY-256 portable multi-channel gamma spectrometer developed by Beijing Institute of Geology, China, as the operating platform, constitutes a γ-ray measurement system with a large-volume scintillation detector. The location of each measuring point with GPS navigation device positioning. The latitude and longitude of the measuring point and the acquired 256 gamma energy spectrum data at the measuring point are collected by the microcomputer of a notebook computer, and the 256 spectra of each measuring point can be displayed in real time while traveling. The instrument is installed in a light off-road vehicle to form a complete car multi-channel gamma spectrometry system. The system has been used for environmental radioactive monitoring after it has been calibrated on the aerial survey radioactive model of Shijiazhuang. The large amount of data obtained indicates that the instrument has stable performance and reliable operation, and is an advanced measure for rapid environmental gamma spectrometry. It not only can be used to determine the concentration of natural radioactive elements in the environment, but also has important significance in emergency treatment of nuclear accidents and nuclear contamination monitoring.
