CORRECTION: SEE CORRECTION APPENDED; Rocketdyne: An article in Friday's Section A about Boeing's Santa Susana Field Laboratory identified Dan Hirsch, co-chairman of a panel overseeing health and environmental studies at the former nuclear testing site, as a physicist. Hirsch is a lecturer on nuclear policy at UC Santa Cruz.

The report also disclosed little-known information about lab operations: It was home to 10 nuclear reactors and numerous low- power reactors, plutonium and uranium carbide fabrication plants and a "hot lab" used for remotely cutting up irradiated nuclear fuel shipped in from other federal nuclear plants.

2006: An independent panel of scientists releases a report that finds the 1959 nuclear accident appears to have been much worse than previously suspected and could have resulted in hundreds of cancers in surrounding communities. It also finds that chemical contamination from rocket engine testing at the site continues to threaten area soil and groundwater.
