This document contains the second part of a series pertaining to the scoping survey conducted between September 1985 and May 1987, of the outdoor surface environment of the Y-12 Plant site. The nature and extent of contamination within each Priority Area was established by assessing three separate criteria. These were (1) gamma exposure rates, (2) concentration of uranium in surface soil, and (3) concentration of mercury in surface soil. In addition, a limited number of soil samples were analyzed for the presence of polychlorinated biphenyls (PCB's). The results of the survey showed the presence of radioactive materials, principally U-238, in many areas of the Y-12 Plant site. The presence of mercury contamination was also confirmed. Use of survey data to develop strategies for reducing radiological contamination on the Y-12 Plant site includes further evaluation, clean-up, and/or changes in current handling practices for U-238. Certain corrective actions have been and are being implemented to prevent the escape of additional radioactivity to the environment. Contamination of clean areas is preventable through heightened awareness and appropriate training of employees and other individuals whose actions may impact the site. Knowledge of the environmental impacts of potentially hazardous substances, including radioactive materials and toxic metals, has increased considerably since the late 1970's. Regulations and guidelines designed to prevent environmental damage and human exposure have subsequently been made more stringent with the increased knowledge and with growing public concern for the potential hazards involved. Diagrams of the designated Priority Areas of the Y-12 Plant site, tables, and charts are included.
