Shuttered Radiation Lab Poses Ongoing Health Risks for Growing Neighborhood

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.

非营利组织称:保护华埠长者免受气候灾难影响 需要更多资金

极端天气事件近年来造成许多严重破坏和人员伤亡。 2022年,欧洲热浪及南亚、西非和中非的洪水导致数千人死亡;2023年,夏威夷茂宜岛发生的野火是美国有史以来死亡人数最多的火灾之一,夺走了100条人命;加拿大野火造成成千上万人流离失所,迫使美国对超过1亿2000万居民发布空气品质警报。

尽管全人类都受到自然灾害的影响,但美国环保署警告,因为既有疾病、免疫力低下、行动不便和其他健康问题,包括老年人在内的部分人口面对的风险比其他人要高。

Destroyed Records, Dying Witnesses Consign San Francisco Radiation Lab to Obscurity

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.

Human Radiation Studies Included Mock Combat, Skin Tests and a Plan to Inject 49ers

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 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.

After Atomic Test Blunder, Government Authorized Study of Radiation in Humans

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 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.

A Community of Color Contends With the Navy’s Toxic Legacy

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.

How a San Francisco Navy Lab Became a Hub for Human 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.

Part 1, the series overview, was co-published by the Guardian. Listen to the two-episode “Exposed” podcast, which will be broadcast on KALW Public Radio. See also: Parts 2-6, laying out the origins, methodologies, ethics, documentation and public health legacy of the lab.
