EI-3500M Channel Door Type Radiation Detection Systems
Product Instruction
Eastimage is an industry-leading provider of security inspection products and safety solutions. Established in 2003, the company has 50,000 square meters of independent property rights of the production base. After more than 20 years of development ，Eastimage has become a major supplier and a leading R&D and manufacturing base for security products in China.
The EI-3500M is a set of automatic monitoring system for radioactive materials with large volume and high sensitivity gamma-ray
detector. It can make real-time and online detection for the vehicles (automobile or train) through the detection channel, find traces of the radioactive materials, output the alarm information of over-limit radiation automatically, and complete storage of test data. At the
same time, the system can also be networked with higher level management system, which constitutes a remote real-time detection
information system platform. The system can be used in imports and exports channels of various places to detect whether vehicles and containers contain radioactive materials.
Environmental conditions
★Operating temperature ：-30°C ~ +50°C, humidity: < 95% (no-condensing) ★Ingress protection ：IP65
★Main service voltage range ：110-240 VAC, single phase 50-60 Hz (< 1 A)
Technical Parameter
★Application areas ：customs , ports, docks ，airports , etc.
★Detector Configuration 1 ： two or four sets of plastic scintillators + double low-noise photomultipliers, each crystal with the sensitive volume of 25, 30, 50 or 60 L. Add 5 mm of lead (five sides) to block out the interference of the background on measurement. Neutron detector is available;
★Detector Configuration 2 ：four or eight sets of NaI (Tl) scintillators + low-noise photomultipliers, each scintillator with the sensitive volume of 2 L. Add 10 mm of lead (five sides) to block out the interference of the background on measurement. Neutron detector is available.
★Detection of γ and X rays ：energy range of 25 keV ~ 3 Mev;
★Signal processing unit of controller：32-bit embedded ARM9 processor, can be used to enquire the system state and information on site;
★Sensitivity：under the background level of 0.2 μSv/h, add 0.1 μSv/h, and sound the alarm of radiation within 1 s; ★Detection probability：≥ 99.9% (confidence coefficient: 95%);
★False alarm rate ：≤ 0.01%
★Coverage of detection: height--0.1 ~ 4.5 m; width: max. 5 m; ★Standard passing speed: 8 km/h
★Alarm：sound and light alarms (to distinguish radiation alarm from over-speed alarm), with the alarm threshold value adjustable, can be connected to the remote backstage management computer and are equipped with the special backstage management software;
★Recognition of naturally occurring radioactive material (NORM)
★The backstage management computer system can record the passing and alarm data, take a snapshot, print the report automatically, and network with the higher level management department. The automatic identification software for plate number and container umber is optional.
