Monitoring radioactive materials is a significant problem in many fields. The Detector Array determines location of radiation emitters in an area by the temporal evolution of the count rate signal from a radiation sensor read-out by supporting electronics systems during each full revolution of a specifically shaped motorized rotating shielding member. It is mounted to the ceiling or wall to monitor the activity of radioactive materials throughout the room. The device continually measures the spatial radiation field fingerprint and either compares it to the stored trusted template or sends it encrypted to a central decision making location. Upon statistically significant deviation from the template spatial fingerprint, either an alarm gets tripped (or the device stops sending cryptographically signed “still OK” messages), depending on security system architecture.
- Monitors materials through direct detection of gamma and neutron emission
- Creates a 3D radiation map or “fingerprint” of the room/area
- Adapts radiation “fingerprint” to movements made by a trusted authority
- Signals alarm when movement occurs without trusted authority present
- U.S. Patent Nos. 9,881,708 and 9,978,469
Technology Readiness Level:
- TRL 4: Basic technological components are integrated to establish that the pieces will work together.
The Multi-Channel Analyzer Application (MCAA) is a Windows-based software program that allows a user to operate a multi-channel analyzer set to collect gamma spectra. These measurements are critical for quantifying residual radioactive material or completing radiation surveys of a working space. The software creates a connection between a tablet/personal computer and a multi-channel analyzer, allows configuration of measurement settings, automates critical quality control checks, and saves the acquired spectrum in a variety of file formats for later analysis.
- Full-energy spectrum display in real time with programmable regions of interest
- Compatible with multiple detectors from low to high resolution
- Saves output in Snapshot, HMS4, and HMS3 formats for analysis
- Full touchscreen functionality with Windows 7 and 10 compatibility
- Detector HV and gain settings controllable through user interface
- User interface designed around HMS4 for familiarity
- The Y-12 National Security Complex has copyright protection for this technology.
Technology Readiness Level:
- TRL 8: The system has been built and tested, and it can be demonstrated.
Novel wireless sensor system enabling a new breed of smart city research and sensor-driven environmental science
The Waggle research project at Argonne National Laboratory seeks to design, develop, and deploy a novel wireless sensor system, with the aim of enabling a new breed of smart city research and sensor-driven environmental science. The software and hardware designs from the Waggle project are used by the Array of Things project, which is building a smart city and open data with urban sensors in Chicago. The project recently received a $3.1 million grant from the National Science Foundation to support the development and installation of 500 sensor nodes. The nodes will initially measure factors such as barometric pressure, light, carbon monoxide, ambient sound, and temperature. Continued research and development will help create sensors to monitor other urban factors of interest such as flooding, precipitation, wind, and pollutants
