Remote Radiological Surveys and Documentation for Environmental Restoration Activities
R. C. Free, Jr.
The Canyon Disposal Initiative involves the decommissioning of large spent fuel reprocessing and chemical separation canyons on the Hanford Site. When conducting decommissioning and environmental restoration work, an essential element of a successful radiological control program is obtaining and documenting representative radiological survey data in hazardous environments. This is especially challenging when the work is performed remotely in retired canyon facilities. The Hanford Environmental Restoration Contractor uses a variety of radiological survey techniques and methods to obtain accurate radiological survey data remotely. In addition, digital photography is used to provide the detail necessary to accurately document the radiological information obtained. This paper describes the planning and techniques associated with obtaining quality radiological survey information in support of high-risk radiological characterization activities. Additionally, this paper describes the application of digital photography and remote instrumentation to accomplish this work and maintain worker exposure As Low As Reasonably Achievable.
