摘要
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。
The car-borne multichannel gamma-ray spectrometric system Model CZD-6 is composed of a HDY-256 of portable multichannel gamma-ray spectrometer developed by the Beijing Research Institute of Uranium Geology and a large volume scintillation detector. The position for each measurement point is determined by the GPS instrument. Its latitude and longitude, as well as measured 256 channels of γ-spectrometric data are collected by a notebook computer, which can show the 256 channels of spectra for each point during measuring processes. The complete system can be loaded in a field car. This system has been used to environmental radioactive monitoring after calibration by airborne radiometric models in Shijiazhuang,Hebei province. A lot of data confirm that the system works stably and reliably, and is a fast and advanced approach for environmental γ-spectrometric monitoring. It can be used not only to determination of contents of natural radioactive elements in environments,but also to monitoring nuclear pollution and emergency treatment in nuclear accidents significantly.
