| Summary: | This report is prepared by the National Research Council (NRC) Committee on an Assessment of CDC Radiation Studies. It reviews the draft report, Task 4. Environmental Pathways-Models and Validation, submitted in 1993 by the Radiation Assessment Corporation (RAC) to the Centers for Disease Control and Prevention (CDC). The RAC's report describes the methods RAC plans to apply in a dose reconstruction project at the Feed Materials Production Center (FMPC) at Fernald, Ohio. The facility, which is northwest of Cincinnati, operated from 1951 to 1989. During that time, there were discharges of uranium compounds and small amounts of other radionuclides to the atmosphere and to groundwater and surface water. The goal of Task 4 of the project is to develop a method that can be used to translate the release estimates into actual concentrations of radioactive materials in the environment surrounding the facility and to predict the radiation exposures to human populations living in these environments
