Santa Susana Field Laboratory

Rocketdyne Worker Health Study

In the late 1990s, the University of California Los Angeles (UCLA) released studies on potential impacts of radiation and chemical exposures to Santa Susana Field Laboratory (SSFL) workers. The study was conducted by UCLA, overseen by the California Department of Health Services (DHS) and funded by the US Department of Energy (DOE).

At the time the UCLA studies were released, current and former employees raised many questions about the results of the study. In order to address employee questions, Rocketdyne and the UAW initiated the Follow-on Rocketdyne Worker Health Study in 1999. A group of outside experts, making up the Science Committee, were chosen to oversee the study and the International Epidemiology Institute (IEI) was selected to conduct the follow-on study. Rocketdyne, the UAW, the IEI Research Team and the Science Committee presented the study results to employees and retirees on April 7-8, 2005.

The IEI Research team found no consistent or credible evidence that employment at Rocketdyne had adversely affected worker mortality.

The Science Committee likewise concluded that, based on the results of the study,

  • The Rocketdyne workforce had a much lower overall mortality than the rate observed in the California population
  • There is no evidence that working conditions caused increased mortality in the Rocketdyne workforce
