She Had an Ulcer. Doctors Lied, and Injected Her with Plutonium.

from The Truth of the Matter with Natasha Zouves · host Natasha Zouves

What was supposed to be a short hospital stay turned into a nightmare that would follow one family for generations.   41-year-old Janet Stadt entered a hospital in Rochester, New York, seeking treatment for an ulcer. She never consented to becoming a human test subject. Yet in 1946, doctors secretly injected her with plutonium — a radioactive element used to build atomic bombs — to study how it behaved inside the human body.   Stadt was one of at least 18 Americans injected with plutonium during the early days of the Cold War, when scientists were racing to understand the effects of nuclear materials on humans. Just a little over five feet tall, she received the highest dose of all the test subjects. The plutonium remained in her body for the rest of her life, causing crippling pain and unexplained illness. For decades, Stadt suffered repeated cancers and extreme medical complications. Her family was never told the truth. Her family now says they suspected she was a hypochondriac, or “making it all up” until years later, when a mysterious box arrived on her grandson Jon Stadt’s doorstep, revealing what had really happened.   In this episode of "The Truth of the Matter," investigative journalist Natasha Zouves sits down with Jon Stadt to uncover the hidden history of America’s secret human radiation experiments — and the devastating personal toll they left behind.   Watch here https://www.youtube.com/watch?v=VSmK1GKAuWo&list=PL6PrA6lo8rJIaFbc0VZfFz4xcY8d6vaR6&index=1   Follow the podcast on IG: https://www.instagram.com/truthofthematterpod/   The Truth of the Matter with Natasha Zouves isn’t just another podcast — it’s a fight to uncover what powerful institutions want hidden. From secret human experiments the government carried out on unsuspecting citizens to toxic cover-ups poisoning communities, Emmy and Murrow Award-winning journalist Natasha Zouves brings you the stories people in power don’t want told. Each week, we expose evidence buried in archives, amplify the voices of those who’ve been silenced, and hold the powerful accountable. From radioactive “oatmeal experiments” on children, to cancer causing chemicals destroying farms, to veterans erased from history — these are the stories that matter. This is journalism that refuses to look away. The Truth of the Matter is about transparency, and justice for the people left behind.   Connect with host Natasha Zouves   WATCH the St. Louis investigation part 1: https://www.youtube.com/watch?v=L7_-G_q3wEc&t=1s   WATCH the St. Louis investigation part 2: https://www.youtube.com/watch?v=upYvUe6hWEk&t=817s   READ the full St. Louis investigation: https://www.newsnationnow.com/us-news/military/did-government-poison-st-louis/   You can find “The Truth of the Matter” wherever you listen to your podcasts: https://podcasts.apple.com/us/podcast/the-truth-of-the-matter-with-natasha-zouves/id1804707066 https://open.spotify.com/show/2iQ85VHlMmBfLBaTtSp8tF   This podcast is put together by: Ryan Kerr Allie Purser Mia Balbin-Cuesta Kate Lindermann Richard Bodee Natasha Zouves         Connect with host Natasha Zouves
