摘要
介绍了自行研制成功的既可用于建筑材料和环境空气放射性检测 ,又可以进行现场石材勘探、评价 ,还可用于核设施周围环境以及事故发生情况下γ剂量进行监测的放射性检测仪。该仪器以AT89C5 2单片机作为控制核心 ,选用φ5 0 mm× 5 0 mm Na I(Tl)闪烁计数器配 GDB4 4光电倍增管作为γ射线探测器 ,可连续进行 2 5 6点的全谱测量工作。
This new radiation monitoring system can be used to monitor the radiation of building materials and the radiation of atmosphere, to explore and evaluate rock for building in the field, and this system can be used to monitor the γ irradiation near the nuclear establishments in the average situation and in the serious situation of a radiation incident have happened. The control core of this monitoring system is SCM-AT89C52, andγ-ray sensing head consists of scintillatorφ50mm×50mm NaI(Tl)and PMT GDB44. This system can be used to measure the whole γ-ray spectrum of 256 channels.
