US DARPA takes delivery of 'dirty bomb' detectors from Kromek


The US Defense Advanced Research Projects Agency (DARPA) has taken delivery of 10,000 personal radiation detectors (D3S) from Kromek, under a contract awarded in February.

D3S detectors have been delivered to support DARPA’s SIGMA programme, which aims to prevent attacks involving radiological 'dirty bombs' and other nuclear threats worldwide.

The programme has successfully developed and demonstrated Kromek’s D3S network, which can detect the tiniest traces of radioactive materials.

"We are proud to be part of the successful SIGMA programme which has sought to increase radiation detection capabilities."

Kromek CEO Dr Arnab Basu said: “We are proud to be part of the successful SIGMA programme which has sought to increase radiation detection capabilities while lowering the costs, in order to network an unprecedented number of advanced detectors and provide a comprehensive, dynamic and automated overview of the radiological environment.

“As we announced earlier in the week, it is also pleasing to know that our success in the SIGMA programme has resulted in Kromek being awarded a contract by a different US defence agency to produce a ruggedised handheld radiation detection device to be used for military applications in the US and globally.”

Earlier this year, DARPA successfully demonstrated the bomb detectors at a transportation hub managed by the Port Authority of New York and New Jersey.

Over the course of a month, the system significantly increased the hub's ability to identify sources of radiation compared to currently installed systems, Kromek said in a statement.

SIGMA has also been refining algorithms to improve the radiation-sensing technology in its devices.
