Summary/Abstract

Over 120 million vehicles enter the United States each year. Many are capable of transporting hidden nuclear weapons or nuclear material. Currently deployed X-ray radiography systems are limited because they cannot be used on occupied vehicles and the energy and dose are too low to penetrate many cargos. We present a new technique that overcomes these limitations by obtaining tomographic images using the multiple scattering of cosmic radiation as it transits each vehicle. When coupled with passive radiation detection, muon interrogation could contribute to safe and robust border protection against nuclear devices or material in occupied vehicles and containers.

Summary/Abstract

The problem of detecting a nuclear weapon smuggled in an ocean-going cargo container has not been solved, and the detonation of such a device in a large city could produce casualties and property damage exceeding those of September 11, 2001 by orders of magnitude. Any means of detecting such threats must be fast and cheap enough to screen the millions of containers shipped each year, and must be capable of distinguishing a threatening quantity of fissionable material from the complex loading of masses of innocent material found in many containers. Here we show that radiography with energetic X-rays produced by a 10 MeV electron accelerator, taking advantage of the high density and specific atomic properties of fissionable material, may be a practical solution
