Vehicle Based Radiation Detection Systems

RADPatrol is based on NUVIA Dynamics’ expertise in radiation measurements taken from moving platforms (fixed-wing and helicopter platforms and vehicular). The algorithms provide observed data recalculation to the ground level, real-time identification of selected radionuclides, alarms and intelligent navigation and survey guidance.AIRIS_GFS_HKO

The System provides unique algorithms and techniques, including real-time dose recalculation to the ground level, selected Isotope Identification, Plume tracking, countering and studies of contaminated areas and air, etc.

RADPatrol system can be used for a number of different radiation surveillance tasks, including but not limited to:

  • Area monitoring and background radiation mapping
  • Search and recovery of uncontrolled radioactive source
  • Detection or radionuclides and isotopes identification
  • Radioactive plume tracking and air contamination
  • Contaminated area and local accident investigation

The system comes in three versions designated models, namely Airborne (A), Ground (G) and Stand Off (SO). Several of these are described here.

Airborne (A)

This section describes the airborne detection and data acquisition capabilities.

DETECTION MODULEAIRIS

A standard Detection Module consists of 2 units [each has 2x 4 Liter NaI(Tl) scintillation crystals]. The Detection Module can be set according to aircraft parameters and surveillance tasks. Each crystal is equipped with an individual Multichannel Analyzer. Each box performs independent recording of the raw data to internal memory.

The system is self-calibrated and energy stabilized in real-time.

DATA ACQUISITION

Data Acquisition is set on a rugged laptop, allowing the operator to control surveillance parameters, including map-view navigation, real-time data acquisition and alarms, real-time spectra and other.

PILOT NAVIGATION

The AIRIS system is equipped with PGU (Pilot Guidance Unit) that provides the pilot with sufficient information about survey flight parameters, including cross-track information, distance to go to the next way point, guidance along survey lines, etc.

In particular, for tasks such as plume tracking or contaminated area study, the PGU will automatically form survey lines according to observed data. The system warns the pilot in case of approaching zones where the trespass might be dangerous for flight crew. The system will suggest an escape direction.

Ground (G)

RADPatrol  for ground applications is a compact tool that can be used for radiation detection and mapping purposes. It provides continuous measurements synchronized with GPS timing and location. The collected data is ready for mapping and reporting right after a mission.

Compact and easy to deploy, the system can be set in any type of vehicle for various radiation detection and monitoring tasks. The system can be installed in a vehicle, cargo area, trunk, roof cargo compartment, or on an ATV type platform.

The system is suitable but not limited to the following applications:

IRIS_cart_blue

  • After event contamination mapping.
  • Area monitoring and background radiation mapping.
  • Mapping in agricultural and industrial zones.
  • Search and recovery of unattended radioactive sources.
  • Potential radiological threat search.
  • Environmental studies.
  • Nuclear sites radiation safety monitoring.
  • Radiation protection and control tasks.

RADPatrol System Description

The system consists of components for detection of radioelements as well as data acquisition and storage as described below.

DETECTION UNIT

IRIS

A standard Detection Unit consists of 2 of 2 Liter NaI(Tl) scintillation crystals. The Detection Unit can be customized with different size crystals and/or an energy compensated GM tube. The Detection Unit standard is set in a rugged plastic case, equipped with wheels and a handle.

The Detection Unit can be connected via Bluetooth or Ethernet interface to the Data Acquisition system. Independent of the Data Acquisition system, the IRIS Mobile Detection Unit can continuously record observed raw data to internal memory.

The system is self-calibrated and energy stabilized in real-time.

DATA ACQUISITION

Data Acquisition is configured on a rugged laptop, with data acquisition functionality that allows the operator to control surveillance parameters, including map-view navigation, real-time data acquisition, and real-time spectra in a chart or waterfall view.

The collected data is ready for mapping and reporting right after a mission. The data can be exported to ASCII, Binary or KMZ format for post-mission visualization with third-party GIS applications.

RADPatrol / SO

RADPatrol is a Stand-Off Integrated Radiation Information System recently designed as a SORD system that can be quickly and easily deployed in a wide range of SUV or VAN type vehicles for emergency, first-response, homeland security or any other type of CBRNe surveillance. The compact one-box detection module installed in the trunk of a vehicle provides effective detection of gamma and neutron radiation sources.

The rugged laptop based data acquisition module, uses NUVIA Dynamics designed algorithms providing different features, including (but not limited to) directional radiation recognition, isotope identification based on selected isotope library, real time data visualization and tracing, customizable event alarming, dynamic and static data acquisition modes and data transmission to the reachback center.

CBRNe_Interceptor

The RADPatrol / SO can be adjusted to pursue different radiation surveillance tasks, including but not limited to:

  • Street patrol and security tasks
  • Search and Recovery of uncontrolled radioactive sources
  • CBRNe Emergency First Response support
  • Undercover area monitoring
  • Real-time data plotting on the map
  • Illegal radioactive material transportation
  • Dynamic and Static monitoring of significant sites

RADPatrol / SO System Description

DETECTION MODULESIRIS/RADPatrol-SO Internal View

A standard Detection Module consists of two (2) NaI(Tl) scintillation crystals – 4 Liter volume each, energy compensated GM-detector tube, and Neutron detector. The Detection Module can be placed in a vehicle trunk/cargo area on a shock-absorbing plate. Each crystal is equipped with an individual Multi-channel Analyzer. The Detection Module performs independent recording/backup of the raw data to internal memory.

DATA ACQUISITION

SIRIS_operator_computer

A Detection Module has either wireless or Ethernet communication with the Data Acquisition system installed on a rugged laptop. The laptop can be fix-mounted in the cabin. The Data Acquisition system provides sufficient information for the crew, including real-time selected channel data tracing on the map, customizable alerts and notifications, detection confidence monitor, real-time isotopes identification, etc.

Customizable audio and flashing alerts can be set for each mission. The system will notify the operator when the event is present. The system also provides safety alarms, alerting when the area with a dangerous radiation dose level is detected.

The system offers dynamic and static mode data acquisition. Collected data can be transferred to the reach-back center at any time during the mission.

DATA QUALITY CONTROL AND EXPORT

NUVIA Dynamics Inc. has designed supporting software that provides the capability to review, replay, reprocess, visualize and export data collected during surveillance.

The Data Quality Control and analysis tools are useful to verify and re-evaluate observed information. The possibility to visualize multiple channels simultaneously, allows the operator to evaluate and confirm identified contamination areas. The data can be exported to GIS and ANSI N42.42 formats for following visualization and reports.
