G. Spence, D.G. Ford, and W.S. Charlton, "Advanced Radiation Detection Sensor Development at TAMU," Poster presented at the Academic Research Initiative Grantees Conference, Washington, D.C., April 2008.


The growing violence in terrorist attacks has resulted in a greater awareness of the threat of nuclear and radiological terrorism. Securing the borders from any attempt to transport a nuclear or radiological device into the U.S. is a critical need and requires the application of the vast array of technical capabilities at U.S. universities. Current detector technology is inadequate for several important smuggling scenarios including the interdiction of shielded high -enriched uranium (HEU) being smuggled in cargo or on a vehicle into the U.S. [1]. This necessitates the development of advanced detector systems that fully integrate all available signal information with inverse analysis simulations to provide revolutionary improvements in the state of border monitoring technology. Researchers at TAMU are developing advanced radiation detection sensors and detector deployment approaches using a coupled system-ofsystems method (Fig. 1). Monte Carlo simulations have been used along with signal processing coupled to inverse transport algorithms and informed by social science modules.
