SIGMA Deployment Test of 1,000 Detectors

- On a recent sunny fall day in the nation’s capital, several hundred volunteers-each toting a backpack containing smartphone-sized radiation detectors-walked for hours around the National Mall searching for clues in a “whodunit” scavenger hunt to locate a geneticist who’d been mysteriously abducted. The geneticist and his abduction were fictitious. But the challenge this scavenger hunt was designed to address is real: The need to detect even small quantities of radioactive material that terrorists might try to bring into an urban area with the intent of detonating a “dirty bomb,” or worse. By getting volunteers to walk all day looking for clues, the DARPA-sponsored exercise provided the largest test yet of DARPA’s SIGMA program, which is developing networked sensors that can provide dynamic, real-time radiation detection over large urban areas.
A key element of SIGMA, which began in 2014, has been to develop and test low-cost, high-efficiency, radiation sensors that detect gamma and neutron radiation. The detectors, which do not themselves emit radiation, are networked via smartphones to provide city, state, and federal officials real-time awareness of potential nuclear and radiological threats such as dirty bombs, which combine conventional explosives and radioactive material to increase their disruptive potential. Following a demonstration earlier this year with the Port Authority of New York and New Jersey involving more than 100 SIGMA sensors, the 1,000-detector deployment in Washington, D.C., marked the largest number of SIGMA mobile detectors ever tested at one time and a demonstration of the program’s ability to fuse the data provided by all those sensors to create minute-to-minute situational awareness of nuclear threats.

those are badass gprs based data relay
The small size of that CsI crystal does not make it an effective tool for wide area search, there are products that can rapidly detect activity over a wide area.
just put them in cell phones then you will have radiation detection everywhere
the barges that turn color if put that in all phones with a app the calls cdc if it gose off what so hard a bout that
or track people in real time
Only if they are radioactive.
I imagine drones have been considered for this once and again many times.
Damian - ABSOLUTELY - That would be a GREAT APPLICATION for this technology - imagine a swarm of drones scouring an area using an air mapping algorithm - smart thinking Damien.
Lance Winslow This is Darpa we are talking about. They invented the medium we are communicating through so I'm confident they already have systems in place I'm not even able to imagine right now. Beetle robots in the sewers? ^_^
Yeah, but that would be too expensive and there would definitely be some serious public outcry.
Krnka You could just deploy them when needed. Pretty sure nobody would complain if it was exceptional and for their safety. I'd be more worried for the drones getting shot or butterfly-net-stolen. An RC car would be more battery efficient though. But the risk would be even higher! ^_^
way too complicated.... as the tech shrinks it can be built into mobile phones and instead of a scavenger hunt there could be a game to find imaginary monsters and Darpa could program monsters to be found where they need a concentration of sensors. ........ uh oh......
narrator could be a voice-double for Sam Harris
Get it done. If they send them to Omaha NE id help 4sure. :)
I wanted to do this
i laugh hearing people worried that DARPA wants to collect as much information as possible about everything. they wont miss a thing. THANK YOU DARPA
tam arinds I wear a tinfoil cap solely due to this ideology.
we to do more of this throughout our country as well as use this tech to find illegal communications and broadcasting
