Our investigative series, “Exposed: The Human Radiation Experiments at Hunters Point,” details how the U.S. Naval Radiological Defense Laboratory, based at a shipyard in San Francisco, exposed at least 1,073 dockworkers, military personnel, lab employees and others to radiation in technical exercises and medical experiments early in the Cold War.

In part 6, we detail how cavalier attitudes toward radiation exposure and an indifference to how pollution left by the Navy might affect San Franciscans have been constants officials warned of plutonium blowing in the air three-quarters of a century ago.

Our investigative series, “Exposed: The Human Radiation Experiments at Hunters Point,” details how the U.S. Naval Radiological Defense Laboratory, based at a shipyard in San Francisco, exposed at least 1,073 dockworkers, military personnel, lab employees and others to radiation in technical exercises and medical experiments early in the Cold War.

In part 5, we trace the obscure nature of the work at the lab to the military’s culture of secrecy, explore why officials shredded millions of pages of paper records and show how an ongoing lack of official interest in acknowledging this history has frustrated local people dealing with the shipyard’s environmental legacy.

Cold War Scientists Pushed Ethical Boundaries With Radiation Experiments

Our investigative series, “Exposed: The Human Radiation Experiments at Hunters Point,” details how the U.S. Naval Radiological Defense Laboratory, based at a shipyard in San Francisco, exposed at least 1,073 dockworkers, military personnel, lab employees and others to radiation in technical exercises and medical experiments early in the Cold War.

In part 4, we examine the ethical implications of the lab’s use of radioactive substances on humans, when neither scientists nor study participants knew enough about the risks to offer informed consent — and how taking such gambles may have seemed more excusable in an atomic-age context than today.

In part 3, we show how the lab’s scientific agenda expanded from monitoring workers’ occupational exposures to using radioactive substances in mock atomic combat and clinical experiments that included topical, oral and intravenous administration of potentially harmful isotopes.

In part 2, we examine public records that prove that exposing humans to radiation was part of the known cost of the lab’s research program, a toll accepted by top military and civilian brass at every level of the chain of command, from Washington down to the docks.

In the first of two podcast episodes of “Exposed: The Human Radiation Experiments at Hunters Point,” reporter Rebecca Bowe traces the soil contamination plaguing a Navy shipyard back to its origins — 20th century nuclear bomb tests in the Pacific.

Environmental justice advocates, scholars and military officials describe their experiences battling over land redevelopment, and reckoning with the legacy of a radiation laboratory that sometimes used human subjects.

In the second of two podcast episodes of “Exposed: The Human Radiation Experiments at Hunters Point,” reporter Rebecca Bowe lays out what we know from scattered documents and a few remaining eyewitnesses about a Cold War research program that pushed ethical boundaries in the name of national defense.

Bowe speaks with veterans who describe their experiences as guinea pigs in field decontamination exercises that yielded little useful data, and talks with colleague Chris Roberts about what the surviving record say about tests involving injection and ingestion of radioactive substances.

Perhaps no local issue in this election is more contentious than Proposition K, which would close the Upper Great Highway to cars and move it closer to becoming a park.

Supporters and opponents have sparred over how the measure’s passage would affect traffic in San Francisco. To find out what’s true, we examined multiple studies, and spoke with their authors and experts not affiliated with the city.
