Selected site contamination history. Final topical report

This is the Final Report that contains the ``Selected Site Contamination History`` for the project titled ``Development of an On-line, Real-time Alpha Radiation Monitor for Liquid Streams.`` It consists of a summary of sampling data for nine locations at the Oak Ridge Reservation. These nine locations were chosen to be representative of those expected across the DOE Complex, and were selected from three distinct Oak Ridge facilities: the Oak Ridge National Laboratory (ORNL); the Y-12 Plant; the K-25 Plant (the old Gaseous Diffusion Plant). The location selected from ORNL is the influent to the Process Waste Treatment Plant (PWTP). This location is representative of those Wastewater Treatment Plants that process water that is known to be radionuclide-containing. The location selected from the Y-12 Plant is the City Flow Monitoring Station. This location represents those sanitary sewer discharges from the DOE Complex that are routed off-site to a civilian waste water treatment plant. The seven locations selected from the K-25 Plant consist of various storm drains and surface waters that are tested during the normal course of K-25`s environmental monitoring program. These locations represent the varied surface waters that are tested for radioactivity levels across the DOE Complex. Final ranking and prioritization of these sites will result in a final selection of at least four sites for testing of the Thermo Alpha Monitor during Phase 2 (the Optional Phase) of the current program. It is anticipated that testing will include the ORNL, PWTP, the Y-12 City Flow Monitoring Station, and two of the K-25 surface water sites
