The RC/400 Charge Bucket Radiation Detection System was designed specifically to detect the presence of a shielded radioactive source during charge bucket loading operations, when the source is uncovered in the scrap load or on the magnet/grapple, and BEFORE the source is loaded into the charge bucket. In the basic configuration, the system consists of a microprocessor controller, one or morge large detector assemblies, remote console and wireless communication system. The detector assemblies will be mounted in close proximity to the top of the charge bucket opening. The detectors will scan on a continuous basis the scrap in the bucket and each scrap load as it approaches and falls into the bucket. (Note: The scrap must free fall into the bucket when the grapple/magnet is above the lip of the charge bucket in order to maximize the detection of a low level radioactive source). This method of scanning scrap is extremely effective because of the low scrap density as it falls through the air into the bucket.

The RC4000 Radiation Detection System is finely tuned instrumentation specifically designed to detect radioactivity in scrap material. The revolutionary design of the RC4000 incorporates 18 years of engineering design and field application experience in order to provide the Metals Industry with the best safety record to-date. The RC4000 incorporates state-of-the-art components and the most advanced software/hardware technology currently available. The system Menus are based on a Windows environment in order to allow a clear and precise understanding of the RC4000 Operations without the requirement of a background in physics. The software is extremely flexible, allowing the user to easily configure the system general operations such as setting of passwords, adjustment of detector parameters, pinpointing the location of a radioactive source when detected, and the storing and retrieval of alarm information. In addition, the RC4000 controller performs all non-real-time tasks such as the management of data received from the detector assemblies and configuring of the system operational parameters. The revolutionary design of the individual high-speed micro-based RC4000 detector assemblies allows performance of all real-time tasks such as pulse analyses from the detectors and vehicle speed measurement. This individual detector functionality is an extremely important and desirable feature of the RC4000 system. In order to achieve the high level of detection capability the RC4000 provides high-speed real-time signal processing and alarm analyses are performed simultaneously with no interruption of the radiation monitoring process.

RC4000 Detector Features

The RC4000 series of radiation detector assemblies provide an extremely high degree of detection capability for a wide range of radioactive elements commonly associated scrap metal. The detectors utilize large plastic scintillation panels that are sensitive to Ionizing radiation. The geometrical shape of the detectors has been designed specifically for monitoring the wide range of vehicles that carry scrap metal.
