This SBIR focuses primarily on monitoring intermodal sea containers. The proposed solid-state detector is also suitable for other deployments, including embed in cell phones for a widely dispersed distributed detection network, or in planned devices such as the Intelligent Personal Radiation Locator. Furthermore other conveyances such as passenger and cargo planes, over-the-road trailers and rail cars can also be monitored with the proposed detector. This detector takes advantage of opportunities for long-term signal detection and integration to detect even low-level or well obscured threat signals. The proposed design uniquely meets the low power consumption, long battery life commercial requirements for tracking and monitoring of goods transported globally. The detector proposed will meet efficiency and sensitivity goals and be useful for real time monitoring of background neutron flux.
