1. 1 Introduction USG – 573 RMDS - Radioactive Material Detector System

2. 2 RMDS - Introduction Radioactive Material Detection System (RMDS) for seaports, airports and land border crossings. The system was type tested for compliance with the IAEA technical guidance (reference manual 2006) and ANSI N42.38 standards

3. 3 Installation of RMDS in Haifa, Israel as part of the MEGAPORT Initiative

4. 4 System Features  Capable of screening passively, every vehicle and its contents while in motion.  Drive through unmanned operation (usual traffic flow, speed up to 8 km/h - 5 Mph). Consists of up to 32 detectors NaI(Tl) 3” X 3”’ successfully integrated into two shielded Isolated stands with thick lead casing inside. Neutrons detection by integrated He3 detectors. Two pillars, 50x40x450 cm each. Easy to assemble and disguise in the surrounding. System output: Audiovisual detection alarms, Isotope identification, Materials location.

5. 5 System Features II Minimization of false alarm rate of less then 1:6000, by unique software which processes correlation of 32 detectors. Prevention of innocent alarms by spectroscopy and Detection probability rate is better then 99% for Cs137 (15 µCi) and Co60 (7 µCi). (According to Beta site testing). Simultaneous Isotope identification of Norm and Hazardous materials also in the drive trough mode due to high efficiency of the detectors. Location of source is available due to multitude of detectors. Completely automatic self calibration without the need of radioactive source.

6. 6 System Features III Energy range is 25 kev to 3.0Mev. Functional in high background fluctuations. Saves history data (spectra, events) for any required period of time. PC-based technology. Communicates locally and remotely via Ethernet communication or dial-up modem. High availability of parts in case of malfunction (COT’S). Electronic seal reader integrates cargo description and origin for variable risk level analysis.
