摘　　要：研制了一种专门用于放射性恐怖活动和放射性物质非法转移的新型放射性物质检测装置。该系统采用非常稳定和可靠的探测材料,对放射性物质具有较高的探测灵敏度和很强的方位辨别能力,检测下限为本底的2~3倍,能量30keV^2.5MeV,响应时间0.5s。其检测信息能通过有线或无线进行网络传输,实现远程控制与监测,并具有体积小、质量轻、拆装方便和使用灵活等优点,已被安检部门用于放射性物质的监测。Radioactive materials inspection system which is applied to inspect the horror activities of radioactive materials and its illegal transfer. The detector sections are made of highly stable and credible material. It has high sensitivity to radioactive materials. The inspect lowest limit of inspection is the 2~3 times to the background, the energy range is 30 keV^2.5 MeV and the response time is 0.5 s. Inspection message can be transmitted through wired or wireless web to implement remote control. The structure of the system is small, light and convenient. It is ideal for protecting society and public from the harm of the radiation.
