General Description
RanidPro 200 is a mobile radiation detection, identification, and data collection system. It consists of a rugged laptop computer, a gamma radiation detector and a neutron radiation detector with their associated electronics. Data and analyses may be viewed on-board with the laptop user screen or transmitted digitally/electronically to a remote station. In addition, a mobile telephone or PDA may be used as an additional remote device to control and monitor the system in operation. The RanidPro 200 is designed to be used in the field unnoticeably and it utilizes a conventional rugged laptop computer and smart telephone as easy user interfaces. It may be powered by a variety of AC or DC supplies. The RanidPro 200 system continuously collects, analyzes, and displays radiation information that is acquired by its detectors. All of the collected data is also stored into an on-board database for later review and/or more detailed analyses. The fully integrated system is driven by the RanidPro 200 software which has been specifically developed for ease of use and to provide high quality field spectroscopy, real-time monitoring, and quick efficient data communication with low identification false alarm rates. Although the system is designed to be very easy to use after a short training period by non-technical users it also contains an expert mode including analysis tools for the advanced user. Bluetooth connections between the laptop computer and a smart telephone with graphical interface forms a reliable communication link to, for example, a remote operation center.
Technical Description
The RanidPro 200 uses employs quality detectors (Lanthanum Bromide for gamma and Li-6 enriched crystals in a matrix of Zinc Sulfide phosphor for neutrons) to provide high resolution information. These detectors may be exposed to a changing environment during use, which could cause energy calibrations to drift. RanidPro 200 addresses this with continuous internal calibrations. The detector data are analyzed using the software suite specifically developed for the RanidPro 200. The gamma analysis is performed using a hypothesis test, analyzing for specific radionuclides. The device contains an extensive radioisotope energy library and also performs ROI summations and count rate normalization.
