Exposed Part 2: the Human Radiation Experiments at Hunter's Point from SF Public Press
Making ContactShow Notes
In Episode 2 of "Exposed" from our friends at San Francisco Public Press, we explore a little-known chapter in San Francisco's nuclear era: human experiments carried out to assess the health effects of radiation. Scientists from the Naval Radiological Defense Laboratory, located at the Hunters Point Naval Shipyard, designed and executed at least 24 experiments that involved gathering data from humans — in some cases, injecting test subjects with radioisotopes or having them ingest fluids laced with trace amounts of radioactive materials. Even football players from the San Francisco 49ers were enrolled as test subjects in these so-called tracer studies. We hear from military veterans who were sent on a mysterious mission to spread radioactive substances onto rooftops at an Army base near Pittsburg, Calif., for an experiment the radiation lab played a role in designing. Some recount experiences of witnessing nuclear bomb blasts in the Nevada desert. We also examine a national pattern of human radiation experiments revealed by Eileen Welsome, the author of a Pulitzer Prize-winning investigation, who shined a light on similar practices conducted by government facilities, hospitals and other institutions. This miniseries first aired on Making Contact in February 2025.

A criminal conviction doesn't end when the sentence does. Across much of the United States, a felony record can cost you your vote, your seat on a jury, and your shot at housing, jobs and professional licenses, sometimes for life. This week on Making Contact, we trace felony disenfranchisement and the "collateral consequences" of a record back to the Black Codes and the post-Civil War state constitutions, and ask why these laws still fall hardest on Black Americans. We hear from Nicole Porter of The Sentencing Project, UC Davis law professor Gabriel "Jack" Chin, and Tamora and Lance Wissinger of the Florida Rights Restoration Coalition, who describe life after conviction in their own words. Content advisory: one segment describes sexual assault by a police officer.

When a supermarket closes, you'd expect another grocer to move in. But across the country, chains write restrictive covenants into deeds and leases that bar any competing grocery store from opening on that site, sometimes for decades after the original store is gone. Advocates call them zombie covenants: the store is dead, but the restriction lives on. They help explain why so many low-income neighborhoods and communities of color are still waiting on a place to buy fresh food. This week we trace the story from white flight and redlining to today's consolidated grocery industry, hear from a former Whole Foods purchasing chief about why chains treat stores like ATMs, and follow the fight over California's AB 1857, the Grocery Store Access Act. Plus what cities from Chicago to Woonsocket, Rhode Island have tried, and what a public grocery store could look like.

Much Western coverage treats October 7th as the beginning of the war in Gaza, but the conflict reaches back more than a century. In this encore edition, historian Rashid Khalidi, author of The Hundred Years' War on Palestine, walks through the early history of the Zionist movement: how founders like Theodor Herzl and Ze'ev Jabotinsky described their project in colonial terms, why British imperial strategy made Palestine a priority, and how the movement found new patrons in the United States and the Soviet Union as Britain pulled back. The episode opens with a report from Gaza by longtime Pacifica and Making Contact reporter Rami Almeghari. Originally aired April 2024; casualty figures cited reflect that time.

To serve in the U.S. military as a non-citizen, you have to be a lawful permanent resident, and many are told that service is a path to citizenship. For thousands, it became a path out of the country instead. Since a 1996 immigration law took away judges' ability to weigh a person's service against a conviction, veterans have been deported under every administration, Democratic and Republican alike. This week, three veterans tell their stories, and two immigration lawyers explain the machinery behind them: what "aggravated felony" actually covers, how a path home opened under the Biden administration, and why it has now closed. Featuring: James Lynwood Smith II, Marine Corps veteran and documentarian, cofounder and director of Black Deported Veterans of America; David Bariu, Army veteran, deported to Kenya, now a naturalized U.S. citizen; Hector Barajas, Army veteran and founder of the Deported Veterans Support House in Tijuana; Michael J.
