We make low cost, networked radiation detectors for federal and local security departments for detecting nuclear materials to better protect our borders and cities from nuclear threats.

This solution requires a small, low power, cheap, and highly sensitive radiation detector.
We have developed a new method using electronic properties of carbon nanomaterials that can dramatically reduce the size of radiation detectors, increase their performances, lower costs, and enhance portability. 
Helping governments to reduce the risk of nuclear terrorism with networkable, low cost, ultra-sensitive ionizing radiation sensors.
