How many people died from caesium-137 in Goiânia? The tragedy behind Netflix’s new global hit series

It’s one of those things we learn about in school, but over time, the details get a bit fuzzy. Then, all of a sudden, the whole world starts talking about Goiânia again. The series “Radioactive Emergency” exploded onto Netflix, cracked the global top 10, and sparked that curiosity everyone has but few can answer properly: just how many people died from caesium-137 in Goiânia? And what happened to that cursed place?

Let me fill you in, because I’ve lived through each chapter of this story up close. Not in the 80s, obviously, but I’ve seen the long shadow this disaster cast across the streets of the Central-West region. Now, with the series making waves, it’s like the ghost of caesium has decided to show its face again. And the question you hear most in bars, on WhatsApp groups, and in the comments from people binge-watching the show is always the same: how many people died from caesium-137 in Goiânia. So let's set the record straight.

The official number and what it doesn’t tell you

If you google it right now, the cold, official number that pops up is four deaths directly attributed to the contamination. Four people. But anyone from here, anyone who saw that glowing blue dust in a child’s hand, knows that number is misleading. It doesn’t come close to measuring the real damage.

The four direct fatalities were: Leide das Neves, the housewife who rummaged through the scrap and found the lead canister; Maria Gabriela Ferreira, the six-year-old girl who played with the glow of caesium and became the face of the tragedy; Israel Batista dos Santos, the security guard; and Ademar Alves Ferreira. They died in the first few months, between late 1987 and early 1988. But the blunt truth is, the toll was much higher.

If you start counting the trail of illnesses, the cancers that emerged later, the depression, the stigma, and the suicides of people who couldn’t live with the fear or guilt, that number goes up. Many people speak of dozens of deaths in the following years that were directly linked to the accident. Caesium doesn’t just kill instantly. It eats away slowly. And that’s the part anyone looking for a guide on how many people died from caesium-137 in Goiânia needs to understand: it’s not an exact number. It’s an open wound.

Where did this nightmare happen, and what are those places like today?

A lot of people watching the series or reading old articles get curious about the locations. What became of 57th Street in the Aeroporto district? And what about Devair’s scrapyard? Well, the story lives in those places too.

The main site, 57th Street, still exists, but it’s not the same. After the contamination was discovered, the area became a massive decontamination construction site. Many houses were literally scraped off the map. The soil was removed. What’s left? Today, part of that area has been redeveloped, but the land where the old Goiânia Vigilância building stood—where the capsule was first breached—remains a silent landmark. It’s one of those places you drive past and feel a shiver, even though nothing looks wrong.

If you’re looking for a review of how many people died from caesium-137 in Goiânia regarding the current situation, you’ll see it’s not just about the past. The so-called "affected areas" are still monitored by the National Nuclear Energy Commission (CNEN). Some areas remain cordoned off, decades later, with radiation warning signs. The biggest example is the waste site in Abadia de Goiás, in the metropolitan region, where all the contaminated waste was dumped. That place became an open-air nuclear cemetery. You can only enter with authorisation and a dosimeter in your pocket.

What the series "Radioactive Emergency" changed in Brazil’s view?

What really hit me was seeing the series break out of its bubble. The news reported it entered Netflix’s global top 10. And honestly, I thought no one outside of here cared about this anymore. But the world was shocked all over again. Even those who usually follow audience trends noted it had a strong debut, even against fans of a certain South Korean group everyone knows. Why does this matter?

Because the series, with its suspenseful, exposé style, brought back a pain we try to forget. And it brought a new crowd—people not from Goiás, who didn’t live through it—asking: how many people died from caesium-137 in Goiânia? What was just a paragraph in a textbook became a topic of debate on social media.

And here’s the wild part: seeing the people of Goiânia themselves commenting. There are people living in the Aeroporto district today who had no idea they were walking where Leide found the device. There are younger folks who are only now grasping the gravity of it, seeing the story turned into entertainment. It’s strange, but it’s also educational.

The legacy: more than just numbers

When people ask if we’ve "moved on" from caesium, I say no. We’ve learned to live with the scar. If you look at the measures Brazil put in place afterwards, it was a turning point. The law banning the scrapping of radioactive equipment, the creation of emergency protocols—all of that came after 1987.

But what really gets me, and what I think everyone reading this guide should take to heart, is this: it’s not enough to know how many people died from caesium-137 in Goiânia if you don’t understand what they represent.

• Leide: the accidental discovery, the mother just trying to make a bit of money.
• Maria Gabriela: the innocence that paid the highest price for a pretty glow.
• The waste pickers: the invisible face of a country that didn’t pay attention to its own trash.
• The neighbours: entire families forbidden from taking anything from their homes, because even the clothes on their backs were condemned.

So, the next time someone asks you how many people died from caesium-137 in Goiânia, you can tell them: "four in the first few months, but the disaster killed the peace of an entire city." That’s what the series, at its best, tries to show. And that’s what we, who love this sun-drenched, welcoming Goiânia, can’t let become just a cold statistic.
