Available in paper copy and microfiche. (Volume 2) contains the Source Term Development. This volume contains the radiological characterization data, spreadsheet analyses, and radiological source terms. The source terms characterize the radionuclides and activity concentration levels for the facilities, and serves as input to the various radiation exposure pathways and scenarios used to estimate the individual annual radiation doses that could result from release of these facilities. Based on the results of these evaluations, it is determined that the application of the proposed authorized limits for the 190-C trenches and the 105-C process water tunnels represents a safe and cost-effective approach to their final disposition.iii BH 1-00844Rev.
