Epidemiology program at the Savannah River Plant: a tiered approach to research

The epidemiology program at the Savannah River Plant (SRP) uses a tiered approach to research. As research progresses from lower through higher tiers, there is a corresponding increase in study complexity, cost, and time commitment. The approach provides a useful strategy for directing research efforts towards those employee subgroups and health endpoints that can benefit most from more in-depth studies. A variety of potential exposures, health endpoints, and employee subgroups have been and continued to be studied by research groups such as Oak Ridge Associated Universities, Los Alamos National Laboratories, Centers for Disease Control, SRP's Occupational Health Technology, and the Du Pont Company's corporate Epidemiology Section. These studies are discussed in the context of a tiered approach to research
