The efficacy of teleoperated gamma-ray and vapor sensors was tested for the timely, non-invasive characterization of buried radiological waste before its removal. Conventional nucleonics and chlorinated vapor sensors were adapted for a teleoperated vehicle that functioned as a remote sensor and a characterization system. Radiological and chemical data were collected at the Idaho National Engineering Laboratory (INEL) on the Radioactive Waste Management Complex (RWMC) and we found that the method fell short on specific characterization. Soil overburden accounts for this shortfall as this overburden intentionally shields hazards as well as needed detailed characterization data. A simple, gamma-transport calculation based on our RWMC data indicates that the remaining sensor signatures are sufficient to supply radiosource size and isotope types during site remediation.
