DARPA tests smartphone-sized sensor’s ability to detect radiation


One agency program announced this week that it has now developed and tested wearable cost-effective devices that can detect radiation. Those sensors would be part of the Defense Advanced Research Projects Agency’s SIGMA program, focused on creating a continuous radiation-monitoring network that could cover a city or region. SIGMA said it has “successfully developed and demonstrated” networked, low-cost smartphone-sized devices that can detect radioactive materials, and be paired with larger detectors attached to major infrastructure or inside cars.
