Kromek, the UK-based radiation detection specialists, has had successful partnerships with the US Department of Defense’s Defense Advanced Research Agency (DARPA) and the Defense Threat Reduction Agency (DTRA) as well as the US Department of Homeland Security’s Countering Weapons of Mass Destruction Office (CWMD), in developing the D3S hand-held Radioisotope Identification Device (RIID) and its successor, the D5 RIID, which is the smallest, lightest and most accurate handheld device currently available.

“American research and development funding has allowed us to design and manufacture these revolutionary devices in record time,”, explains Craig Duff, Kromek’s CBRN Business Manager. “Handheld RIIDs have transformed the way radiological hazards are detected and analysed at a time when the radiological threat is increasing.”

As a result of this extensive cooperation with US government agencies, more than 10,000 of the D3S handheld units are currently in operation in North America. They are a key component of DARPA’s SIGMA programme which is a long-running programme to develop and deploy a high-performance, networked radiation detection capability in a variety of scales and scenarios.

In June 2021 the D3S RIID was an essential component of the security sweeps around the US Air Force One aircraft as President Biden toured Europe. Both the D3S and the D5 RIID can be integrated into any legacy or new-build electronic information system as well as SIGMA.

Kromek has also partnered with some of the leading US National Laboratories including Oak Ridge, which proved the radiological algorithms for the built-in isotope library in the D5 RIID.

Launched in 2020, the D5 RIID has 24+ hours of battery endurance with thermal and vibration sensitivity and has already captured a sizeable US market share, with over 2000 devices deployed by the Port Authority of New York and New Jersey, including at JFK, La Guardia and Newark airports, and at the World Trade Center.

This summer, the D5 RIID is being used across the United States of America in the multi-agency exercises Patriot and Indian Head to simulate preparedness for a radiological disaster or attack.
