Scatter in Cargo Radiography

As a complement to passive detection systems, radiographic inspection of cargo is an increasingly important tool for homeland security because it has the potential to detect highly attenuating objects associated with special nuclear material or surrounding shielding. Detecting such objects relies on high image contrast between regions of different density and atomic number (Z). Threat detection is affected by scatter of the interrogating beam, both in the cargo and surrounding objects, which degrades image contrast. Here, we work to determine the extent to which scatter plays a role in radiographic imaging of cargo containers.
