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

The Model RD-150 Vehicle Based Radiation Detection System (VMRDS) 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. 

The Model RD-150 VMRDS is uniquely flexible, allowing quick setup and transfer from different vehicles. The modular approach with independent detector packaging enables a plug-and-play simplicity to adapt vehicles to a particular application. Detector positioning allows 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 most popular User Interface option for the Model RD-150 is PeakAbout, the Berkeley Nucleonics Smartphone Application 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 PeakAbout 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.

At the core of the Model RD-150 is a high-performance MCA featuring DSP electronics and a high-voltage control system for an 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 before final hermetic seal to ensure that efficiency is optimized.


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 unprecedented confidence. These improvements are particularly useful with high-sensitivity (large volume) NaI and moving applications where background shifts are common.


In addition to powerful spectroscopic data analysis and reporting, the Model RD-150 with the included PeakAbout App interface gives users features to address the larger situational needs. The full ANSI N42 report can be quickly examined, and then “Pushed” to a management team, reach-back office, or series of several incident support options. Users can easily suspend the data acquisition to take pictures and videos, thereby including situational inputs in the spectroscopic report. Additional software hosted in the user’s application gives real-time tutorials on an isotope-by-isotope basis to add credibility to the user’s disposition options. This focus on the larger application requirements differentiates PeakAbout and BNC’s line of Nuclear Radiation Detection Instruments.
