2 Radiation Detection Systems: The RC4000 series of detection systems utilize advanced technology we call Energy Specific Alarm Threshold Setting software algorithms in addition to our long-time Total Count and Shape Recognition alarm algorithms. The RC4000 is extremely sensitive to low level radiation emissions from a moving vehicle regardless of the severe changes in background caused by varying scrap densities. Another extremely important issue is for the system to recognize and eliminate the ambient background interference from the ground, brick building and concrete structures. This will significantly improve the system detection capability while virtually stopping false alarms. The RC4000 system technology has been proven to be the best system that is currently available for monitoring any type of scrap metal shipment. The RC4000 systems are installed and monitoring at more than 2,500 Steel Plant and Scrap Processing facilities worldwide with a perfect record when it comes to detecting and protecting these facilities from Radioactive Gauges. Important Notes: All of RadComms series of radiation detection systems is Network-able with full remote access for system monitoring, data viewing and retrieval, servicing and electronic adjustments. Introduction The RC4000 Radiation Detection Systems are finely tuned, revolutionary, instrumentation that has been specifically designed to detect radioactivity contained in a moving vehicle loaded with scrap material. The revolutionary design of the RC4000 incorporates 18 years of engineering design and field application experience, and provides the Metals Industry with the best safety record to-date. The RC4000 incorporates only the best state-of-the-art components and software/hardware technology available in the world. The System Menus are based on a Windows environment, allowing a clear and precise understanding of the RC4000 Operations without having a background in computer science or physics. The software is extremely flexible allowing the user to configure the systems general operation such as; setting passwords, adjusting detector parameters, pinpointing the location of a radioactive source when detected in a vehicle, storing and the retrieval of alarm information. The revolutionary design utilizes high-speed micro-controller/cpld technology in each detector assembly. A multiple of electronic adjustments such as gains, high voltage, noise filters and thresholds can be made via the PC display screen, telephone modem and/or network/ethernet connection. The detector electronics utilizes modular designs allowing fast and easy replacement of parts should a problem arise. The RC4000 PC windows based software is extremely flexible with easy to follow menus in the language of the country where the system is being used. The menus include Graphical Alarm data, total system configuration, manual scan mode, power outage tracking, nonradioactive testing, etc The RC4000 system is by far the most advanced radiation detection system currently available.

Temperature Monitor: System must monitor the internal temperature of the detector and display and continuously record in memory Performance Specification of the RC4069 Response: Will detect a 55KBq (1.0 uci 137Cs point source) at 1 meter from the face of the detector (the radiation exposure level is comparable to a 75mmΦ x 150mm 3.7GBq (100mCi) 137 Cs Lead Sealed Source buried in 0.7 g/cm 3 of scrap metal). Detection: The RC4069 Radiation Detection System has been designed to detect very low-level radiation in vehicles carrying all grades of recycled and waste materials. The RC4069 detection system in controlled testing will reliably detect 10 times out of 10 any sealed or unsealed radioactive source such as 137 Cs, 60 Co, 192 Ir, 226 Ra source buried or unburied producing an exposure rate of 0.05mR/hr or 500nSv/hr on a surface area of 12 x 12 or 30 x 30cms on the outside side wall (84 /2.1m) of a vehicle from 39 or 100cms away when the vehicle is traveling at various speeds of up to 3 mph or 5 km/h. RadComm reserves the right to make, within reason, any adjustments to the system to achieve the performance specification. RadComm's overall detection capability will be significantly increased as vehicle speed decreases. SPECIAL NOTE: All of RadComm s radiation detection systems have been field proven to detect the level specified in the Performance Specification outlined in this document. There have been many recorded incidents where radioactive sources with lower exposure rates have been detected but the level of reliability cannot be determined and is therefore not specified in the performance specification.
