SAMmobile 150 (RD-150) Vehicle-Mounted Radiation Detection System

1Description

The Model RD-150 Vehicle Based Radiation Detection System offers users a quick integration of spectroscopic nuclear detection capability in existing response vehicles. Large volume, highly sensitive gamma and neutron detectors are integrated into shock-absorbent packaging for reliable mobile monitoring. The unified monitoring system is scalable with multiple detector point options in your existing vehicles. Results in simple form, backed by full spectroscopic reports and identification details, are available to the vehicle operator in real time. Detector positioning enables optimized detection geometry for pinch points, freeway passing, lot scans or other clandestine monitoring requirements.

The detector modules are tied to a comprehensive user interface running locally or remotely. Scalability of systems with this size and sensitivity is a first in the mobile detection industry.

The Model RD-150 comes standard with PeakGo, a PC-based software interface which conveniently illustrates isotope and isotope class-specific, color coded peaks and bar graphs. The app is free and included with all shipments of Berkeley Nucleonics’ Nuclear Detection and Isotope Identification products. The rich feature set in PeakGo includes GPS Tagging, photo/video report appending, pop-up isotope help and “Push-to-Reachback” functionality. In addition to PeakAbout, users may elect to integrate alarms or push-functions to existing communications and reporting systems.

4System Hardware

At the core of the Model RD-150 is a high-performance MCA featuring DSP electronics and a high-voltage control system for optimum dynamic range. The digital processor is supplemented with an analog anode output to enhance timing functionality. The processor is a 32-Bit RISC with excellent data acquisition and processing functionality. The entire electronic module is packaged in a shock-reducing enclosure. The photomultiplier tube and NaI detector are matched prior to final hermetic seal to ensure that efficiency is optimized.

5System Firmware

The data processing and management is extremely efficient and leverages several proprietary processing and post-processing techniques. A unique Wavelet Transform gives users a strong confidence level on a wide range of isotopes without being limited to a peak search in a Region of Interest (ROI). The concurrent background correction and background subtraction, two separate algorithm enhancements, give second-by-second analysis and unprecedented confidence. These enhancements are particularly useful with high-sensitivity (large volume) NaI detectors and moving applications where background shifts are common.

6System Software

In addition to powerful spectroscopic data analysis and reporting, the Model RD-150 in tandem with PeakGo gives users all the functionality they need. The full ANSI N42 report can be quickly examined, and then forwarded to a management team, reachback office, or a series of several incident support options. Users can capture pictures or video during data acquisition, allowing for a more complete spectroscopic report. Additionally, real time tutorials on an isotope-by-isotope basis are included with the RD-150. This focus on the larger application requirements further differentiates PeakGo and BNC’s line of Nuclear Radiation Detection instruments.

7Application Software – PeakGO

The PeakGO application software is compatible with any Windows platform. It graphically displays details about identified isotopes and a map derived from GPS data. Alternatively, an Android-based application software can be used for smartphone.

The Main Screen presents real-time gamma dose rate, neutron status, and count activity at a glance. The Event Log Screen records each alarm and its location, building the database protocol for log files and alarm events. Captured pictures or video from data acquisition append to the spectroscopic report.

The Spectrum Analysis / ID Screen plots the measured spectrum and reports the identified isotope, category, and confidence, illustrated here with a Cs-137 identification at 100% confidence. The Map Screen plots GPS-tagged measurements over a route map for freeway passing, pinch points, and lot scans.

Together these screens deliver real-time spectroscopic reporting in the field, with the full ANSI N42 report available to forward to a management team, reachback office, or incident support.
