Journalist Chris Roberts discusses the long-forgotten history of the U.S. Naval Radiological Defense Laboratory at San Francisco's Hunters Point Naval Shipyard. Following atomic bomb tests in 1946, the Navy towed radioactive ships to San Francisco, creating a research program that exposed more than a thousand people to varying levels of radiation. Roberts' seven-part series in the San Francisco Public Press, "Exposed," details how the lab conducted human experimentation with questionable consent, incomplete record-keeping, and environmental contamination that plagues redevelopment efforts today. The former shipyard remains a Superfund site marred by cleanup fraud scandals, while surrounding communities face potential health impacts that remain largely unstudied.
