D3Mtm The ultra-low false alarm rate personal radiation detector A high-performance combined gamma-neutron, Personal Radiation Detector that protects against the (accidental) exposure to nuclear materials. Field proven design, the handheld D3M is easy to navigate and simple to understand and provides confirmation of exposure to threats. Radiation Detector (PRD) with superior
Applications
D3M – the go-to detection solution for nuclear industry professionals ■ Law Enforcement ■ Fire Departments Customs and Border Patrol ■ Military and civil defence Public security and event monitoring ■ Nuclear industry The D3M is a combined gamma-neutron Personal Radiation Detector (PRD) with superior sensitivity. It continuously scans and monitors the environment for radiological threats and alerts the user when it detects a gamma and/or neutron radioactive source. This rapid-response handheld PRD display screen shows: ■ dose rate ■ gamma alarm ■ accumulated dose ■ neutron count ■ dose alarm
Better Detection
■ neutron alarm The D3M is a powerful combination of two of Kromek's award-winning leading technologies; the non- 3 He compact thermal neutron detector and its world leading gamma detector. Its superior detection capability is due to its large detector volume – I inch 3 Csl(TI) gamma detector. The D3M offers superior sensitivity at 500 cps/(μSv/h) for Cs-137 and has a maximum dose rate of 1 Sv/h @ 662keV. The large detector volume together with the higher sensitivity means that it is better able to detect threats faster than standard PRDs and with minimal false alarms.
Ultra-Low False Alarm Rate
The D3M also comes with an industry-leading ultra-low false alarm rate; more than six times better than the ANSI standard which means less time wasted with nuisance false alarms that can occur with some basic PRDs. It also means the operator is more able to trust the information the device is giving them because when you get an alert it is more likely to be the real thing. When there is an alarm, the D3M alerts the user via a combination of audible, visible and vibration alarms.
Detect Shielded Threats
The powerful neutron detector improves the detection of shielded fissile or special nuclear materials (SNM).
Dose Data Analysis
The D3M can be connected to a computer via USB or Bluetooth for data extraction using Kromek's CIRIS software. An SD card within the D3M detector can store over 100,000 spectral data files. The data can also be used for dose reconstruction, showing dose over time and accumulated dose.
Field Proven Technology
The D3M developed from DARPA's (Defense Advanced Research Projects Agency) SIGMA Program as an extension of the D3S radiation detection device which has over 10,000 detectors currently deployed globally.
Networkable
The D3M is also compatible with DARPA's SIGMA Network when paired with a specialised app on an Android phone. Using SIGMA's web-based user interface, multiple units can be easily tracked displaying any threats in real-time in multiple locations on a map of a specific area from a remote and centralised location by trained experts in radionuclide identification.
Accessories
Ruggedized event cases provide more than just storage and protection for the D3M and charger units, they also enables rapid deployment. Charging stations simplify the electrical power logistics of charging a fleet of devices from a control point. Automated detection and ID with web- based command and control system Standalone charger stations are available for operating from a central control point Ruggedized go anywhere event case that enables rapid deployment
