Researchers are developing portable digital imaging technologies such as digital radiography and computed tomography instruments for custom applications. The team focuses on highly accurate field-deployable systems. This directly supports the INL in hazardous and radioactive waste assessments, and the team has also developed rapid analysis systems for old munitions in storage or those found in excavation. An additional element of this group’s work is expert system software for automated data analysis and data validation for nondestructive nuclear assay. Researchers are assisting the nation’s national security by developing transmission x-ray imaging capabilities to better equip first responders encountering improvised explosive devices (IED’s). Another capability is x-ray fluorescence imaging (XRF) that can be used to interrogate waste containers to determine, and possibly quantify, heavy metal or transuranic content.
