Today we present the first half of a two-part radio documentary from our friends at SF Public Press, "Exposed," opening a window into the little-known history of the Hunters Point Naval Shipyard. The sprawling abandoned naval base, in San Francisco's southeast waterfront Bayview neighborhood, is currently the site of the city's largest real estate development project. The base played a key role in the Cold War nuclear era, when it housed a research institution known as the Naval Radiological Defense Laboratory, which studied the human health effects of radiation.

In Episode 1 of the podcast, we trace the radioactive contamination found in the shipyard soil today back to its origins, with nuclear bomb testing in the Marshall Islands. We also hear from environmental justice advocates, including one who led a health biomonitoring survey revealing that nearby residents have toxic elements stored in body tissues that match the hazardous chemicals of concern identified at the shipyard. It first aired on Making Contact in February 2025.
